It's a bug, it should be fixed soon.
I know this is a dumb question, but is there an app like in the Android market to get cover art?
I had this too on the update.It took 20 out of 587 or so covers from my music and also corrupted the songs too.I had to delete them from phone then drag them back from iTunes library.
----------
I get all my cover art from the internet.Theres loads of great sites which do album cover art.
I thought this too but those 20 songs wouldn,t play anymore and were missing the cover art.After reinstall from my iTunes library they were ok and complete with Cover arthmm idk if an update would corrupt songs.
