Donald Glover unleashed yet another track from his forthcoming Childish Gambino mixtape late Friday courtesy of Philadelphia radio station 96.5. At this rate either the new Gambino mixtape is going to be pretty epic in scope or Glover will have managed to stream pretty much every track from the thing by the time it releases. This newest song “Shoulda Known” is a smooth, low-fi affair with a Casio-sounding beat and Glover’s own vocals laying the harmony in the chorus. Check out a radio rip below.
