A new Mac Miller track popped up yesterday on TreeJay & DJ Clockwork's Smoke Till I'm Dead mixtape. "Headaches + Migraines" features a verse from Dave East and production from Cardo. Miller describes a life of bleary debauchery. Try to move my body but my skeleton vibrates, he raps. Whose car is that and how’d it get in my driveway?/ This is high stakes professional time wasting. Later he asks, why’d you get so high so early?
