Robin Thicke goes “Deep.”

The R&B crooner teams with Nas on his brand new single. God’s Son goes acapella on his powerful intro verse, rapping about police brutality and racial injustice before returning with some scathing words for Donald Trump: “And you don’t think it’s an emergency / A toupée-wearing liar is tryna run the USA.”

For his part, Thicke delivers his silky smooth vocals while singing about relationship issues that just aren’t worth losing sleep over. “It ain’t that deep, we ain’t gotta lose sleep,” he sings over the sound of whistles.

Thicke is in the studio working on a new album, the follow-up to 2014’s Paula. On Oct. 15, he will hit the stage for TIDAL X: 1015 at Brooklyn’s Barclays Center.
