Robin Thicke on Monday evening released a stirring new track "Deep," featuring Nas.

The four-minute cut opens with an impassioned, a cappella series of verses from Nas candidly addressing America's recent struggles with racial prejudice and police-involved shootings of unarmed black men.

While Thicke sings about the struggles of a relationship, Nas is heard taking direct aim at Donald Trump: "And you don’t think it’s an emergency / A toupée-wearing liar is tryna run the USA," he warns.

Nas also seems to predict a Hillary Clinton win in November, advising a female he cares about: "You don't even see what I see in you / The next female president could even be you."

It's unclear if the song is a preview of Thicke's forthcoming album, but he has described it as "my new single."
