Mac Miller raps pure absurdities in a kind of stream-of-conciousness rap that must have actually been given a good amount of thought to pull off.
S.D.S is an abbreviation for "Somebody Do Something". If flying around in a cape with a goggled dog while rapping count as "something", then it appears that young Mac has already taken his own advice.
The track produced by Flying Lotus should appear on Mac's forth coming Watching Movies With the Sound Off.
