Watch the throne. Eminem and Gwen Stefani join forces on “Kings Never Die” off the Southpaw soundtrack. On the triumphant rap-rock hybrid, Em comes for the crown and obliterates the competition with his rapid-fire rhymes (“It’d actually have to be a fuckin’ blowout to get me to retire / Tell these new artists that kings never die”), while the No Doubt frontwoman delivers an anthemic hook: “Here to stay even when I’m gone.”

Due July 24, the soundtrack also features contributions from 50 Cent, Action Bronson, Joey Bada$$, and The Weeknd. The movie arrives in theaters the same day starring Jake Gyllenhaal, Forest Whitaker, Rachel McAdams, and Curtis “50 Cent” Jackson.

Hear the rap god and pop goddess unite.
