Mac Miller finds the girl of his dreams on “Onaroll,” the first single off his collaborative EP with Pharrell, Pink Slime. The Pittsburgh rapper flows over the bombastic beat, produced by The Neptunes hitmaker. “She get good grades, suck good d**k, what more could you ask for?/ Big ol’ butt, love to f**k, what more could you ask for?” raps Miller. See how he rolls.
