My iTunes library has decided to be obnoxious and while listening through a bunch of tracks, one song kept jumping like it was corrupt - as if half a second was removed and then spliced back together. So, being a good little boy I accessed Time Machine, went back a few months, found the file in Time Machine and it wasn't corrupt. Then, just to satisfy my own curiosity, I went out of Time Machine and played the supposedly "corrupt" mp3 direct from Finder using QuickLook and it played fine. The fault at 3:01 didn't exist. Back in iTunes, the song is corrupt and again skips at 3:01. So, clearly there is something in iTunes and not the mp3 itself which is corrupt, no? Any ideas how to fix it?
