Can I add into Playlist Creator a playlist created with iTunes?
Sure, create a new playlist with playlist creator, and instead of adding songs, tap icon at bottom of screen that says Playlist to call up all of your playlists created with iTunes. Select the playlist you want to bring over to Playlist creator, and then select add all songs at top of screen. Or just select the songs you would like to bring over. Then use Playlist Creator to modify, reorder, or remove for the new list.
