Robin Thicke has enlisted Nas for a collaborative new single. The New York rapper tackles America's ongoing problem with police brutality on his opening verse, even detailing his conversation with his own son. "Can't play with your water gun, son, 'cause the police see a 7-year-old as a threat. They think it's right to kill a 7-year-old on sight 'cause he ain't white," Nas raps on the newly released 'Deep.' Listen to their new collab below.
