A Frank Ocean feature
Frank Ocean's features on Watch The Throne ("No Church in the Wild," "Made In America") are among the album's best, and he followed it up with some "additional vocals" on "New Slaves." So we already know the two artists work well together—and if it ain't broke...
Plus, it would be good to have some sort of indication that Frank is alive, breathing, and still in possession of functioning vocal chords. Not tryna rush you, though, Frank. Take your time. Take as much time as you need.
