Cap 1 is getting ready to unleash his latest mixtape, Caviar Dreams, on January 14. He has now released a new song called "They Know," which has the potential to be a big song. It is a collaboration between the Chicago native, 2 Chainz, and Ty Dolla $ign over a beat by Young Chop. Despite the title, the song is actually about the things haters "think they know." Not that 2 Chainz cares about what the haters say. As he reminds them: "Crib so mothafucking big I don't even know where my room at."
