New Music: Alicia Keys feat. Kendrick Lamar – ‘It’s On Again’...

Alicia Keys debuts her Kendrick Lamar-assisted new single 'It’s On Again', lifted off 'The Amazing Spider-Man 2' soundtrack (due April 22nd). It has smooth disco strings and bopping keyboards so it comes as no surprise that the disco-happy Pharrell Williams produced it.

Look out for the track when it drops tomorrow via iTunes and get your first listen inside.
