I have only 4 playlists in itunes. When I sync any songs at all with my iphone, about 20 playlists show up only on my iphone; all old playlists I had deleted long ago. This problem didn't show up until I updated to itunes 11, anyone know how to fix this?
i delete them on my phone but they show up again after i sync, even though they're not on my itunes.
You may want to try recreating your iTunes Library and playlists, as there may be some data in the iTunes database that is displaying correctly in iTunes, but causing problems through the sync process.
