Look up iRip if you get into the position where "it's only on my iPod." Be sure not to sync until you read more about iRip. Sorry, I'm useless too. That is, I don't duplicate the iRip tips and more.
I recently installed internet explorer 10 and it was so buggy that I deleted update and reverted back to IE9. Unfortunately, afterwards although everything else seems to be okay, when I opened itunes, I only have my cloud folder music. Podcasts, music, playlists are gone. I sitll have all these items in windows explorer music folder, but I cannot restore them back into itunes. I also have all these items backed up on my ipod. Please help. Apple is useless when it comes to anything windows.
