I'm one of the few people who actually like the Music tab's interface (using the zoom to scan a song is very nice, IMO) but I have a question about removing songs from the library...
I deleted the stock songs from my device and now, when I go to the music tab, I get the 'searching...' message and, when I go to library, all the old songs are still there, but with exclamation marks rather than album art.
I went to WMP and deleted all the songs in the 'My Music' list, so I know the two aren't tied together.
Edit:
Also, I've added a bunch of music in a folder I created (Storage Card>My Documents>My Music) and neither WMP or the Music tab see this folder. Where do I put music on the storage card so the media players will see them?
Try Deleting the AudioManager.vol file in \Application Data\HTC\AudioManager_Eng. That should force AudioManager to re-search your device for Music (you'll need to disable TF3D and make sure Audio Manager isn't running in the background to delete the file. You also may need to use Total Commander or Resco, however selecting "Show all Files" in File Explorer may also work).
I personally haven't tested it by deleting any files first, but I don't see why it shouldn't work (though you did indicate it shows "Searching" everytime you go to the tab, so this may not work). It's something to try, at any rate.

That didn't work. The deleted songs still show up and it still doesn't see the new songs. You figure they'd want these devices to be user friendly and make it easy to copy your music onto it. Or remove songs you don't want.

I have my Music in \Storage Card\Music (because that's where Windows Media puts them by default when you sync it), and I've never had any problems with AudioManager finding my Music. Perhaps you should elaborate on your setup, ROM-wise.
Stock ROM. Just got the phone a week ago. The songs I'm trying to load are .mp3. I've tried putting the songs on the device directly in the /Music folder, I've also tried /My Documents/Music, /My Documents/My Music (both on the device and on the storage card). The MP3s will play, if I pull them up in TC or File Manager.
I've tried copying the 'Dogbark.wav' file to the storage card (/My Documents) and WMP has no problem finding THAT file. I was thinking it might be a file name issue, but I've tried renaming one of the mp3s to something as simple as one letter and it STILL isn't seen.
Do you NEED to sync it with Windows Media Player? (This is a bit of a problem, as I use linux and don't have ready access to a Windows machine.)

No, you shouldn't need to. I'm really not sure why it wouldn't be working.
What Carrier are you on? What location? There may be a ROM update floating around somewhere that will solve your problem.
I'm with AT&T in Florida. I'd like to avoid a ROM flash, if possible...

I don't know if that's possible, unfortunately. I'd actually suggest a hard reset to see if that fixes the issue. If you're going to do that, you may as well update to the new AT&T ROM. I, unfortunately don't have any other suggestions for you.
Actually, the only other thing I can think of is that it's an issue with your SD card, but that wouldn't explain why AudioManager won't update.
go to the music tab, bottom left softkey "library", slide over to "all songs", and play something on your phone. it should clear off all old songs and the new ones.
I actually found the solution on the AT&T support forums. (HOLY CRAP! Useful information was ACTUALLY found there for once!)
Two words:
Soft reset.
Don't know why I didn't try it sooner.

The problem I was having, Jack, was that the music player wasn't detecting any of the new songs I had on the phone. 'All Songs' was blank, because I had deleted all the songs that were included with the device and it just wasn't seeing the new ones. At least not until I did a soft reset.

I assumed you'd tried that. That's usually the first thing everyone tries, so I didn't even bother suggesting it. Glad you got it working.
i dont like to restart the phone. it takes a really long time to boot up. it always finds the songs with the way i listed. i even have all my album art.

Hi everyone,
Just got my Pro yesterday and generally loving it - with one major problem though.... I can't seem to add music to the device.
If I dump them straight on the memory card then TF3D music tab says "No Music Found", if I sync them over WMP11 to the device then it shows them - but no album art and their durations are all zero seconds. WMP won't play them either. They're just in MP3 format and play fine everywhere else.
Help?
In the TF3d music tab, click on the Library softkey. You should be able to find them in there (under artists, albums, etc). Once you select a song, it will then load into the TF3d music tab. Hope that helps.
Thanks, I can get them to show there but without album art and the duration is zero seconds... WMP Mobile shows an error "access denied" when i try to play them there, if that helps.
I have no problem accessing my mp3s, but I did not use WMP11 to sync them.
I just copied mp3s right onto my microSD card, separated into folders by album (eg: \Music\artist1\album1\song.mp3), with a folder.jpg image for the album art. TF3d/Library recognized the files and the album art with no problem.
Hmmn, tried that, still the same thing. Just hard reset the device and still a no-go. This is beginning to really bug me very badly (like sending the device back kinda bad).
Double post to update:
So, I find that I can add WMA files without a problem. So at least I have a viable work-around for the problem. This doesn't actually help me sort out what the problem regarding mp3s actually is.
I thought it may be something to do with the File Associations, that I broke them somehow by installed Coreplayer, but I'm less sure now that a Hard Reset didn't solve the problem. It still could be, I see others have had similar problems relating to the registry (although their problems always came after installation of a different media player, rather than on the devices stock ROM). Does anyone know where the pertinent registry values are, and what they should be? Or perhaps others have some different solutions?

Have you tried soft resetting and deleting the file
\Application Data\HTC\AudioManager_Eng\AudioManager_Eng.vol
before switching to the TouchFlo Music tab?
Found I've had to rebuild my library in this way each time new mp3s have been added.
(I assume the mp3 aren't DRM protected - copied a number over myself by mistake which caused a similar problem.)
Probably a silly question,
When i synced my phone with Windows media player 11, all the tracks went across but not the artwork. Having looked in the folders on my pc, i see that the folder has an image, but there is no image file to transfer to the TPro. How do i get the artwork across and does this have to be a manual process.
If the album art is in the folder and named folder.jpg it automatically picks them up ardsar.
Thanks for that Lazy Slug, I'll give it a go.

Fancy seeing you here, and sorry didn't mean to hijack your thread, it's a great forum eh!
im using vista with wmp v. 11 and wmp cannot see my touchpro even if it is connected (via bluetooth). i've got no problems syncing mails, calendars, etc. i just cant seem to sync audio files using wmp.
thanks.
Well, my problem is sorted (kinda). I backed up my mp3's to a different external hardrive, something has happened in that process that means they only work on my PC - my PS3 can no longer stream them, my N82 can't play them, my Touch Pro can't either. I'm still trying to work out how to fix them (although when I have time I'll dig up my old drive and see whether they work from there). So good news: nothing wrong with my PS3, N82, Touch Pro.
Regarding your issue dido-11 - have you set up the Touch Pro to sync in WMP11? Instructions are in the manual for how to, if you haven't already tried.
NZtechfreak: indeed, it's in the manual. sorry, quite excited to use it right away without looking at the manual.
fhsieh: thanks, ill try that method as well.

Did you try to reencode one mp3 in standard 128 (not VBR) and see if is played?
They're all constant bitrate, they work when converted to WMA. I don't think its a problem with encoding though, since they worked fine with everything previously.

I am syncing my music with Windows Media Player 11 - it syncs over fine and the image art is there when playing the music in the windows media player on the fuze, but not present in the cover flow app. Where are these images stored? There are no jpgs in the directories where the MP3s are.
Is there ANY other program you can use to sync songs to a TP besides WMP? I've been using WMP, but it keeps on making random duplicates of all my songs, and it's REALLY annoying.
I would greatly appreciate any advice.
Oh and I don't want to just drag+drop, I would like some sort of program.
Thanks.
i agree i moved from a iphone and i got to say its annoying, the way windows mobile phones organize music, and when i use windows media player mobile to update my library it seaches the entire device and grabs even system sounds.
Hmm, I just put my microsd card into my computer and dump all the music I want to listen to (mp3, flak, ogg, what ever) into the music folder to play with the built in player / core player.

Well at least with WMP I can see my music in a "library" setup, as opposed to just opening my music folder which has thousands upon thousands of subfolders. It's just much easier for me (at least the way my music folder is setup) to use a program such as WMP.... but WMP sucks. That is why I am asking for an alternative to WMP.

Thats exactly what I do and it works like a charm. It is easier than using a program in my opinion. Are you doing something wrong? is it giving you trouble moving the files to the microSD card?
When I start Winamp and have my phone plugged in, it detects it and asks if I want to use it to manage my music on the phone. Winamp has a great name out there, maybe it oculd be useful.
I also used Yahoo Music Engine at once point and that worked great, like itunes. I think that whole deal is still around too, albeit Yahoo music has changed a bit, the app was called Yahoo Music Engine.
I have not tried sync with WM11. There must be a simple option or something you are missing. Perhaps it has to do with Media Player on WM6 and the library function. If you scan the device and organize the library to ignore your Windows folder then it probably won't be a problem on the WM11 side.
Does that make any sense?
WM11 is simple drag and drop; the problem is that when it loads music onto your Phone/SD card it puts it into the file structure Artist/Album/Track based off id3 tags. So if your music is improperly tagged or if you have more than one copy of a song like an album and a compilation album you'll end up with duplicates.
Personally I just wipe out the Music folder on my SD card every 2 weeks or so and dump a new playlist onto it. You can use the WMP sort function in the playlist to eliminate any duplicates before you copy them over. You can still add to the card later and it won't reinstall the same file so long as it's not a duplicate on your desktop like I mentioned above.
As for getting rid of ringtones showing up in your library on your phone I use Pocket Player for my MP3 player and it has an "Exclude Directory" option on it so it will only update from the SD card music folder.
Did Wm4 or CE or whatever handle music?
So that whole development time while WM5 was on market and ipod appeared, was MS just sitting there saying, "Well these are business devices let's focus on getting four Excel cells to show up on this ****tay 320x240 screen instead"
Great.
And the even funier part is the new Blackberry virtualization occurring over WM6. If they were so good at business apps then why is this occurring, HELP ME UNDERSTAND hahahhaha
This was all tongue in cheek utterance from a bewildered fan of MS and their spastic roll outs!!!!!
Ok so I've spent over 4 hours trying to find a way to move my music from iTunes to my HTC HD2 with album covers and all...no luck... why in the hell is it so difficult just to put music on your phone...All my songs are mp3's and they still won't go on properly...I tried just dragging them to the music folder through My Computer. I tried using double twists software I downloaded from the phone and I tried the one from the official website.
This is ridiculous considering that my old ass samsung flip phone can sync all my music in just 35 minutes with everything i expect. So much for the Entertainment phone...I would really appreciate if someone can help me out with this before I go on this road trip...
I also tried the music from My Music instead f iTunes and same problem...I have all the songs on the phone but they won't play. Does anyone also know why when your in the Windows Media Player all of your GAME sounds and videos and just random sounds appear if its suppose to be a music player... i am disappointed in this damn phone everything is great except the music players...
Personally, I keep all my music very organised on an external hard drive at home. On there, they are all stored in the folder structure X:\Music\Artist\Album\nn Song Title.mp3. I also have album art for each of them as folder.jpg in the album folder. I'm a bit of a pedant, but keeping it tidy has proved to be a godsend no end of times!
When I want to copy something to my phone, I usually make a temp folder on my desktop so that I can keep the folder structure intact inside that, and copy the albums I want, into their respective artist folders - Desktop\Temp Music Folder\Artist\Album.
Once I've copied everything there, I connect my phone to my PC with the USB cable, and I select "Disk Drive" as the connection type.
Then I simply open my phone's storage card in windows explorer, open the music folder on there (that's obviously already there as I've got loads of music on there already), and I copy the contents of the temp folder on my desktop into that folder.
It's really simple, and it works 100% of the time.
I've seen no end of threads where people are using different software for synching & tagging mp3s, or trying to put mp3s in weird folder structures (or even all of them in 1 folder!!!) and I just don't see why you'd bother.
This method has worked flawlessly for me on a Nokia N95, Touch Diamond, Touch HD and HD2.
Hope this helps mate
My HD2 just searches all storage card for any music files and puts them into library.
Some of them are ringtones and other useless stuff. So I don't want them to be in my music library
Is there a way to choose folder where audio manager should search ?
I'm not sure why your library is showing ringtones. None of mine ever end up in the library.
I had Fring and Talkonout installed on storage card. I both have mp3 files for ringtones.
I deleted them both from storage card and files disappeared but that is not a solution :/

i got the same problem. all music files show in my music library when i pressed update library. +1 on how to choose music folder and disregard the rest.
mine does the same. My HD2 came preinstalled with Who Wants to Be a Millionaire game. The manila audio manager displays all the acc music files that came preinstalled... what a pain....
you can make HTC album to ignore some folders. Do the following:
Go to HKLM/Software/HTC/HTCAlbum/Ignore
and add a sting value with a name (choose whatever you want) and string (here you put the location of a particular folder)
So if I want HTC album to ignore My Music folder on my Storage card, I will add a new string value: name-My Music and string-\Storage Card\My Music
hope this helps
ah forgot to mention soft reset after that
Am I doing something wrong? I did a soft reset and still no exclusion from the folders I specified here:
Ignore not Ignored
Oh, should I rename that folder to ignore? Because my HD2's registry came like that with that folder called ingnored.
Maybe the TMOUS HD2 has the d added? Not sure why they would have done that.

Tap Library - Playlist - New playlist (for example playlist 1)
Tap playlist 1 - Add songs - All songs (on bottom of screen) - select all songs you need - Done
Tap 1 song in playlist 1. Music player will play that song and library will update to playlist 1.
I'm sorry about my English, I'm Vietnamese.
Good English! I understood great.
But, I did what you said about adding a playlist & adding songs and it seemed to work great, but then later I went back to play the playlist & nothing played at all. It is strange that this default player doesn't work anymore since I tried the playlist trick. In fact, when I try to find anything to play, the "Music Tab" just hangs and never populates with MP3s at all. I think I bricked my Music Tab of my HD2 (I don't know if I said that right but it sounded good ). Well, at least I didn't brick the entire phone! Now I am forced to use Windows Media Player for all music, which I don't mind at all, but it was nice to use the other player while on the road.
I may end up trying what they say here:
ruscik said:
Well a lot of people noticed a problem with HTC Music tab. Library shows not only music but ring tones and other sounds. One way to stop it is to hide offending folders. One problem with that is if you hide for example ring tone folder you can not select your ring tones as they are hidden as well.
What I did is as goes. I have music on SD card, also there is tomtom, copilot and some other apps. I have hidden all of the apps that might have sounds so they do not show up in library. Obviously left folder with music not hidden.
That will take care of SD card.
For My Device sounds do steps below:
1. Start from removing your card and then going to music tab so it rescans and states no music found. (Skip to step 3 if you are starting from clean rom)
2. Go to registry editor of your choice and navigate to:
HKEY_LOCAL_MACHINE\Software\HTC\AudioManager_Eng (for german it will be AudioManager_Ger)\Information
Delete all items in that folder. You will not be able to delete Information it self.
If you are on clean rom you will not even have that folder it is created 1st time when music tab finds music.
3. Navigate to:
HKEY_LOCAL_MACHINE\Software\HTC\AudioManager_Eng\Config
In there change:
"device_scan_path_path" from what ever there is to \Windows
"device_scan_path_path_0" from what ever there is to \Windows
"ring_tone_path" from what ever there is to \Windows
What this will do is exclude all files in windows folder. If you have any files in my documents they will show up. I assume if you just put "\" instead of "\Windows" it will exclude entire my device but did not test it.
4. Soft reset, insert your SD card and enjoy.

I didn't want to do it that way, but it looks as if I may have to. I liked the first way better (...HTCAlbum > Ignored...)
(I removed "Music" from my Home Screen Tabs as there was no reason to have it there anymore)
I just create playlist and do nothing else. I needn't edit registry.
Where are they held?
The reason I'm asking is when I put music onto my SDcard no matter what player I use it misses over half of my albums. Itunes to my Ipod has no such conflict. So doing a little research lead me to the meta inf? If a folder gets transferred to storage it should still contain the meta data right? How do you make that data readable to the system?(for the record mizing, uber, miui, and stock all have the same results).
Thanks

How are you putting the music onto the sd card?
From harddrive to folder to sdcard. So all the info pulled from the harddrive should be there? My music collection is very tight. Meaning all songs and album art are held in a single folder. Any ideas?
Are there by any chance any .nomedia files in the folders?
No .nomedia files in any of the folders.
What formats are you using on your music?
.m4a is the file type.
You might've downloaded some aac files from the itunes store right? Are you sure none of them have drm? Android won't be able to read them if they do
Sent from my awesome SGS4G
No aac files and I've never used itunes store. All of my music comes from other free sources. It's weird. I have about 50 albums and half are recognized half are not. The ones that aren't have the correct song names come up and even the correct album name but for some reason the artists name isn't being read.

It might be a tagging issue. Not sure what method itunes uses to tag its files since mp3 files tend to use id3. That's why I'm glad on windows, Mediamonkey handles all the tagging. I have my folder structure really organized so that if I try to look for music from just a computer, no music player, I can find it.
/music/Album Artist/[<Album year>] Album/Track# Track title.
If you can get on parallels or bootcamp and can get mediamonkey on windows I'd give it a shot. I'll tell you how to force an update of the songs' metadata.

My music is organized the same way. I'll give media monkey a try when I get some time. Still gonna try just redownloading my music to the sd card when I get some time as well. I'll let you know how it goes. If you have any other ideas let me know.
Thanks
I have this same problem. I use Winamp to sync with my android. And i made sure using both Winamp and an independent tagging program that all my files have tags (artist, album, cover, etc.) and yet half of them still are not read on my phone. Not by Google Music app, not by Winamp, and not by Samsung Stock Player.
Could it be the file types that dont work?
The ones that DO have Artists reading all have the correct album artwork. The ones that DO NOT have artists according to my players all have albums, but about half of them do not have album artwork (the rest do). I'm not sure what's going on. I think it's an error within the Media Scanner?
(on a side note- if you include the track number in the file name of your song, it will show up as that when playing. I would recommend not putting the track number in the file name.)
Nickcu
I never figured out what's going on. Just learned to live with it. I think I might start playing around with it again and try to come up with some answers. If you figure it out let me know.
Im gonna look into it some more later, but i THINK it has something to do with the file type at this point. But don't quote me on that haha.
Just redid all my music. pulled all Itunes related crap out of the folders and it's still not recognizing about half of them. Gonna try some other stuff later. File type isn't part of it I don't think. It still recognizes and plays just shows up under unknown.
I just looked through mine and it seemed that all the files with unknown artist were in .m4a whereas the ones that recognized the artist were in .mp3
could you check and see if yours is the same way?
