Playlist should restore the old playlists' of its users and give music choice preferences and recommendations based off of the users music
that would nice
also playlist should load tons off music for the old school and new school have all types of genre and have an "easy to use" system so EVERYONE can enjoy the site. Furthermore, playlist can improve by having categories(mini-playlists), inside of one major list for organizational purposes. The best way would be too run a trail and get feedback from that as well.
