I have a few albums worth of mp3s which are corrupt, and I've fixed them up a few times but every so often when I open MusicMatch (not all the time, maybe once ever two or three times I reopen the program) it goes and corrupts the same files in the exact same way on startup. Messes around the ID3 tags and doesn't let me change them until I use an external program to fix them again. Has this happened to anybody else?
