On the chorus of Smoke DZA's "4 Loko," ASAP Rocky takes a break from vaguely self-identifying as a "pretty motherfucker" to give a decent definition: I'm that Harlem motherfucker with that mellow flow. And while that is certainly true of Rocky, Smoke DZA, mugging for the camera in a green Ireland rugby shirt, sounds a little more hurried, though he ends his lines in a creeping drawl. Or maybe it's just the song's gnarly beat that gives it that spookiness, piano like the Jaws theme running dank for three and a half minutes. This one is a bruiser. Grab the MP3 here if you don't have it.
