In 2013, Pusha T revealed to Miss Info that he was going in the studio with The Neptunes (Pharrell and Chad Hugo) for 20 days in Miami to work on tracks for King Push.

Fast forward to 2015, and Pusha hasn’t released anything from those sessions yet. Many fans hoped his new album, Darkest Before Dawn: The Prelude, would have at least one song with The Neptunes. But, they won’t be left empty-handed as he placed a collaboration with Pharrell during the credits of his short film, Darkest Before Dawn. You can listen to it below.

People online have named the song “Switch It Up,” but it’s not the confirmed title. According to Pusha T’s management, it’s also not the finalized version.
