So I export my playlists onto my sd card and everything works fine. Then I go to update the playlist and overwrite the existing copy. However, when I click on the playlist in the music app, it shows both the new and old copy together (For example song 1 from new playlist, song 1 from old playlist, song 2 from new, etc). My guess it that the playlists are being copied onto the phone, but where can I go to delete them? Just deleting them off the app gets rid of the sd card version.
