The beat goes on, Madonna/Pharell collaboration, which was leaked some days ago, is already circulating in New York clubs on a promo CD containing six tracks, supposedly played at Warner meetings last month.

Apparently spinning the song without mentioning it as Madonnas new song, is part of a strategy already used 2 years ago by Stuart Price with the Confessions tracks

"Beat" has been played at Barracuda club 3 days ago.
