Who has Kanye West been in the studio with? Everyone. It will be interesting to see what ends up where. What combination would you most want to see? Kanye West, Mos Def, Diplo, and A$AP Rocky? Kanye West, Hit-Boy, and Jadakiss? Huge, epic posse cut? Avant-garde noise-rap featuring nothing but yelled Khaled vocals over dueling Kanye West/Diplo production?
