Big Sean has recruited frequent collaborator 2 Chainz for his newest track "Light It Up" which finds the two rappers exchanging bars about grinding through the night and hustling despite having already made it.

The Detroit MC has been staying busy in the studio completing work on his new album and looking to the opinions of hip-hop's finest to make sure that it's right. "Going thru my 4th album with one of the masters. Almost ready. Been clique since #Clique," Sean captioned a photo of him and Jay Z. He also shared a picture of him and music wizard Rick Rubin kicking back on a couch with their eyes closed, looking very into the music as they previewed Sean's new tracks.

He was also heard spitting some pretty big bars on a previously unreleased Mike Will Made-It banger the beatmaker previewed in the studio at the end of August, but it's unknown exactly what project that song might wind up on.

"Light It Up" arrives as part of the original soundtrack for Kevin Hart’s new stand-up comedy film, Kevin Hart: What Now?, which officially arrives Oct. 14 and features vocals from Kevin himself as his rap alter ego "Chocolate Droppa" while boasting additional features from T.I., Migos, Trey Songz, Tink, Lil Yachty, Akon, and more.
