Producer: Benny Blanco.
Backstory: After cutting his first track for a porno film, the 23-year-old Virginian (a.k.a. Benjamin Levin) hustled his way into partnerships with producer Disco D and rapper Spank Rock. He was couch-surfing in Brooklyn when über-producer Dr. Luke took him under his wing, helping earn him credits on tracks by Ke$ha and Katy Perry.
Signature Sound: Call it bubblegum rap — bouncy tunes and fluid verses designed to boost adrenaline.
2011 Summer Jam: Britney Spears' "Gasoline".
