So I did the shuffle and now my iPod is broke. It says it has like 6 gigs of music on it... But when I go thru the menus of artists, albums, playlists, suddenly it is all wiped clean. Has tis happened to anyone? I haven't plugged it in to the computer or anything, because that crashed too a few days before. My brother backed up my music on DVDs thankfully. Any idea what happend to the pod?
