New Music: will.i.am f/ Justin Bieber - '#thatPOWER'

will.i.am topped the charts with Britney Spears (“Scream & Shout”), and now he’s calling on another pop megastar for his next hit. The Black Eyed Peas frontman, who turns 38 today, joins forces with Justin Bieber for “#thatPOWER.”

The dance floor-ready record kicks off with a sample of Daft Punk’s “Harder, Better, Faster, Stronger” before the Canadian star comes alive on the hook.

The two recorded the Auto-Tuned track during last month’s BRIT Awards in London. “The collaboration on this song is a doozy, it’s a spectacular one,” will told Capital FM.

“#thatPOWER” will appear on will’s upcoming solo album #willpower, due April 23.
