Sounds like Samsung's Group Play feature.
EDIT: Not really but kind of.
I agree with others, i don't like this idea of patenting the world to basically give yourself a nice list of money earners in patent court.
But the music has to be on your player in the first place. And if you have Achy Breaky Heart on your player you deserve all you get.So you're in the middle of busting a move to the transcendental heights of The Macarena; and what happens? The Roving DJ changes the BPM and your song cuts to Achey Breaky Heart! Sounds terrible.
