Sway's Universe premieres Donald Glover's latest track "One Up". The rapper/actor's upcoming mixtape, Royalty, is due out on July 4th. It wasn't specified who was on the first verse (my guess is A$AP Rocky), however we'll be sure to confirm it soon.
Update: It appears the guest feature belongs to Donald's brother Steve G Lover.
its Steve G Lover on the first verse, he says it. I think it's Donald's Cousin.
@EJtheCroom i think you're right, i remember seeing footage of them performing a song on stage.
