2 or 3 albums in my iTunes are missing. I did not delete them. The playlist is still visible. But ther eis no album art and each song has an "!" before it. I have back up iTunes on dvd. But sadly, I have new apps, songs, and app data that were not backed up. Now I cannot sync my ipod for fear of losing my data. For what it is worth, the missing songs are still on my ipod Touch.
