A Canadian radio station says it's the real deal radio edit, though there have been quit a few fan-made fakes released over the last few days. SONiC 102.9, a rock music station from Edmonton, has shared what it says "sounds pretty damn close" to the official track. Also, Pharrell has some verses on it. What do you think?
My take? Who fucking cares. Press play, enjoy the hell out of it, and have a DANCE PARTY?
UPDATE: Annnnnnnnnnd it's down. We'll see when a new version emerges.
