Pharrell: Heartbeat

As we all know, Pharrell has been nonstop producing tracks and laying down records wether it be for him, N.E.R.D, or other artist. Today, another demo he did with Madonna for her latest album, Hard Candy leaked. The track, Heartbeat, is really good. I'm feeling the demo better then the original. Also, the demo features Nicole Scherzinger on backup, and Pharrell does lead, meaning no Madonna on this track. Be sure to check this out.
