i've been having issues with my ipod touch since updating to iOS 8. at first when i tried to listen to music it would continuously skip songs. i restarted the device to see if it would stop and it didn't, so i then decided to restore it. the skipping problem went away but unfortunately now it won't sync correctly. i've always just selected 'sync entire music library' but doing this nothing would sync. i then tried to manually select artists, and this did work, but playlists wouldn't sync. i restored again to see if i could solve the playlist problem and now artists won't sync correctly either. out of the 6705 songs that are selected and should be syncing, only 1500 of them actually have. i've restored both from various backups and as a new device. also my last.fm scrobbler keeps trying to scrobble songs that have already gone through. what on earth is going on and how do i fix this?
