It would great with a Jukebox function, or public event folder. Where people could add songs to a que. It could have a safe mode button. So the host could chose to approve or decline song request. This could be good in, events, parties, hangouts, ect ect.. And make it involving, fun and a nice way to share music and create unity. It could be a flirt. It would make it easier at parties as to song requests. At home and at pubs. Everyone would have a personal dj in their pockets!
