Childish Gambino‘s Royalty mixtape was packed with collaborations, but this one between Donald and Jay Rock didn’t make the cut. Now thanks to the Trigger Happy mixtape, we can check out “Sour Face.” On the mixtape, from SoSuperSam:

Here’s what I like to play when I’m DJ’ing, what I played on tour with Childish Gambino, what I listen to at the gym.  It’s that shit I do like.  You’ll find some familiar tracks, along with new tracks from Childish Gambino ft. Jay Rock, and Gonage.
