This morning I was trying to play an album, but iTunes was not playing it. For some reason, 3 or 4 songs were working and the rest were not. The album art was not showing for the ones that were not playing either. So I removed the album and then added it again, but this time iTunes only added the 3 or 4 songs it could play before. If I play the files outside of iTunes it they work. For some reason iTunes is not recognizing them. Weird, because the album was working before. Any idea how to fix this? P.S. I have the latest version too.
