Yung Lean’s career has always been plagued by the question: are we supposed to take this guy seriously? Admittedly, there seems to be no clear answer; people write him off just as quickly as they flock to his concerts. However, one thing is for certain, Yung Lean thinks Yung Lean is serious. Very serious. “Shawty U Know What It Do” finds the Swedish sensation rapping over some of his sharpest production yet. Sad Boys producer, Yung Sherman, shines with an otherworldly beat as Lean does his part to complete the song by half singing, half moaning lyrics about Grey Goose, Gucci shoes and white linen with a sad angst that only Mr. Lean can provide.
