You should add the ability to batch edit ID3 tags from within the locker (similar to iTunes). This way you could highlight all the songs on a particular album and change all of the files at once.

Preloading the next track on a playlist. I sometimes use mp3tunes from a slow connection and there is a 5-6 seconds gap between songs, or the song starts playing but it has to stop after a few seconds to load the track. If mp3tunes was pre-loading say half of the next song on the playlist, then there wouldn't be any gaps.
Just an idea.

In the track listing within individual albums in the Android mp3Tunes Locker app, the tracks are sorted alphabetically instead of by track number. They should be sorted by track number so we can actually listen to albums in the correct order.

Currently the you can only shuffle (using MP3tunes player) using a playlist. I prefer to hear the entire album (imagine listening to Pink Floyd's The Wall, Queensrhyche's Operation Minbdcrime or many others as individual tracks). However I do not always want to search through my entire collection every time I just want to listen to music.

I use a Palm Pre :: great phone. I would give my right lung to use my mp3tunes account in a natively written app on the Pre. Currently it is impossible to play anything but the first 18 seconds of songs, and it is impossible to navigate efficiently. Thanks!

If you won't provide FLAC support, at least provide automatic transcoding of FLAC to MP3 in Lockersync so we can have our FLAC-based music "in the cloud". While full FLAC support would be better because of the backup benefits, this would at least be a start.

MP3tunes doesn't seem to use the disc number when playing back an album with multiple discs, it just sorts them just by their track numbers. All track 1's will play first, regardless of their disc number, and then the 2's and so on.

98% of my asian mp3 are without artwork. Even some mp3 with artwork are with the wrong ones. So if there is a add artwork function, would be good

I would like to be able to sync my music OTA to my storage card on Windows Mobile. I only use Windows Mobile and because of coding requirements, I will probably never use anything else.

find a simpler way to create a playlist, it is too time consuming to add tracks

My music collection was, like most others, placed on the shelf, sorted by artist, then albums.

I want my music collection like that! Make it possible to show my albums, but don't sort them by the title of the album, sort them by the name of the artist! That's the way we're used to finding our music (at least the ones of us who had a CD collection.

I uploaded a bunch of files to my mp3tunes locker and then downloaded some stuff back to my computer later. After awhile I had about 300 duplicate files on my local machine and like 2000 duplicates on the web site. I tried to use the TUNE UP area of the web site but, it did not find or delete my duplicates! You seriously need to fix this problem. it takes a long time to upload a lot of files to your mp3tune locker

My files with an accent in the title or the name are not displayed properly.
For example "Múm" or "Sigur Rós".

There's columns for "Artist" "Track" and "Genre" but it's impossible to see an album's title when searching. Some artists have similar tracks on many different albums (especially for composer's soundtracks) and it's sometimes impossible to find the track you want.

Currently, I can stream only one track and will only play once. The playlist and player needs to be fixed so it can play all tracks from the playlist. Remember MediaMaster, that platform was able to do that and hope it can be done here soon. This is something I would like to use for Second Life...
