Earlier this month, Big Sean invited 2 Chainz and Future to listen to his latest album and hopefully earn their blessings. It seems that Chainz didn't only provide his ears during the session, though, as he and Sean -- now longtime GOOD Music partners -- can be heard together on a brand new collaboration, entitled "Light It Up." The song won't be included on Sean's album but is instead slated for What Now? The Mixtape, an upcoming soundtrack of sorts to the stand-up film "Kevin Hart: What Now?," which hits theaters tomorrow (Oct. 14).

Hart will release the "What Now?" tape as the Chocolate Droppa. The Droppa's vocals (which got him a deal with Motown) will be featured on the mixtape, but "Light It Up" only boasts raps from Sean Don and Tity Boi. Good thing -- these two never let us down.

Quotable Lyrics

Sean Don, Perrion, Don Corleone

Hit the vroom vroom every single time the 'Rari on

Riding around in Malibu tryin' to see a Barbie home

Came up from that one bedroom-room, now we on

- Big Sean
