I am using MP11 on Windows 7. I have been updating old MP3 Rips with the proper album info. Getting album artwork and mapping tracks. These are rips from long ago when you songs would just be Track01, Track02... I use Find Album info, map the tracks and all looks good. in abou 5 minutes the Albums reverts back to Track01, Track02. This is driving nuts!!!!!! I am ready to smash my PC. I hate apple but am really tempted to switch to evil iTunes.
