If people were willing to deal with using a program on their PC to tag all of their files with a number that represents the amount of gain that ought to be applied, it would be pretty easy for me to cook something up in emphatic that raises or lowers the volume when the track is played back. The thing is, that's a large ordeal for people with large music collections. Even if we had a way to do it while the song is being played back on the empeg, we can't write to the files unless we mount the drives read-write, which is a bad idea. The thing about the original approach that was tried in earlier player releases is that it was done automatically on the first pass through the track, and stored on the dynamic data partition for us.
