Mac Miller just let a new song go on Twitter called "Cold" featuring his homie Curren$y. Surprisingly, this is their first collaboration ever. Mac sets it off, rapping, "Roll it up, then smoke, now tell me why your bitch look like Glenn Close." Nice one! And of course, the Hot Spitta comes in on the second verse with that fire. Chuck Inglish on the track. Brrrrrrrrr.
