Sure - when you set up a Jukebox, for example 'http://jukebox.today/example', if your friends go to the exact same link, they will see the same Jukebox music player and be able to add songs, play/pause/skip the music, change the volume, or even play the music through their device in sync. They can access the link from any device on any network, and you'll all be connected to the same Jukebox. That make sense?
