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).
