Recently my iPod has been glitching so that I am unable to delete songs off it via iTunes. The same goes for videos, podcasts, and, strangely, playlists. I think that it’s happened before, but somehow fixed itself. I’ve tried unsyncing music but nothing works. I’ve tried going to the menu bar at the top of the Mac screen but there’s no delete option. Is this my old computer, or my iPod, or what?
