If it was do-able I say count me in. I don't know about submissions, would probably be very time consuming to hear hundreds of 30 second files. But I could say that I wouldn't mind having some basic tracks to play at my house, even if it's just some very simple stuff. Would really add to the atmosphere. Though I think you would have to limit it to one jukebox per room, or at least one functioning one. Wouldn't want people to be playing 100 songs at once.
would also give me a reason to play with the sound on, lol.
