This time he produced Alicia Keys' track "It's On Again" for the new upcoming Spiderman movie. You can totally hear Pharrell's hand in this: the song opens with Kendrick Lamar rapping his ass off over a hardrock guitar riff, like it's the last rap he'll ever lay down. Then the music turns smooth again, with Alicia singing over a funky beat.
I wouldn't be surprised if there's a Nile Rodgers guitar riff/solo in there somewhere. Hat's off to you, Pharrell! (get it? hah!)
