On my PC, the file names of all my ripped tunes start with the track number. Even on my downloaded albums, Windows is able to pull the track number for each MP3 file out of the file. So why does my Droid X (Android 2.1) display and play the tunes in alphabetical order by track title? That really isn't the way any Android user is going to want to listen to, say, the cast recording from Rent.
