ENHANCED PLAYLIST MANAGEMENT SUGGESTION:
Provide a means to better manage user generated playlists. Functions such as sorting, duplicate finding, copying and merging user created playlists would be of real value. Maybe even provide a way to do this organization and editing without having to have a playlist in use. Just combining two playlists and identifying duplicates would be very helpful when assembling and updating a list of favorite songs for a particular listener, event, artist or genre.
