Once you analyze your library of music and add the replay gain information to the MP3 files ID3 tags you never need to add the extra step of applying MP3 gain to the files on the player. Some folks did not want to touch their original files for whatever reason.
Agreed that of course MP3Gain works for MP3 files before the update.
There was no clear way to do volume leveling for FLAC files for example. Lossless audio is bit for bit accurate. Now you can have consistent volume for FLAC files played back on Fuze.
