I might have pulled the iPod out while it was syncing earlier, and now when I go to "Music" on my iPod, it displays "No Music", im sure the songs are still on the iPod itself, but just not being showed in iTunes. It still shows 20 Gigs being used should I restore from backup to restore the songs?? and when does itunes make a backup of the iPod?? I read it was evertime its synced it creates a backup, is that true??
