Alicia Keys, Pharrell Williams and Kendrick Lamar film a music video for 'It's On Again' for the "Amazing Spider-Man 2" soundtrack

Amazing Spider-man 2 brings out the big guns as they get Kendrick Lamar, Alicia Keys, and Pharrell together for a smashing feature track entitled, “It’s On Again”. As usual, Kendrick brings a fresh and fierce eruption of an entrance followed by a swooning Alicia Keys vocal all wrapped neatly together by a outer-worldly production by Happy connoisseur Pharrell.
