I have a iPod touch. The iOS was 4.2 so I upgraded the iOS to 6.1.3. Now that I try to sync my itouch only 4 out of 700+ songs show up on my itouch; however, all 700+ songs show up on my iTunes. In addition, when syncing my itouch, it looks like its not completely syncing because there are usually 6 steps it takes to sync. Mine syncing stops at 4 of 6 every time. What can I do to get all my songs and playlists back onto my itouch? Thanks.
