For a musician who spends weeklong writing blocks playing ping-pong and shooting hoops, Benny Blanco manages to stay busy. The producer-songwriter, whose credits include chart-toppers for Maroon 5 and Katy Perry, has filled his schedule since the start of the year, clocking studio time with fellow hitmakers like Paul Epworth (who co-wrote and co -produced Adele's "Rolling in the Deep") Rico Love and longtime collaborator Dr. Luke. Among the artists he's worked with: Ke$ha, for whom he produced an untitled tune co-written by fun.'s Nate Ruess, and Bruno Mars, who's at work on the follow-up to his 2010 breakthough, Doo Wops & Hooligans. The latter session yielded a piano-laced track intended for Mars' new LP.

"I got a really cool song with him. Me and Paul [Epworth] just got together and Bruno wrote an amazing song on top of it. It kind of all came together," Blanco tells Rolling Stone. "It's like some throwback Nina Simone type ****, like 'Sinnerman.' It's Bruno. He can sing the A.B.C.'s and you'd be like, 'Holy ****!' He knows how to vibe."

The funny thing is that Bruno releasing his debut gave us just an appetizer. I fell we're really unprepaped for what it's coming. It's gonna be unbelievable, I know it already. I'm getting more impatient each day, cuz it's just sooo SOON.
