Back in June, the soundtrack for the upcoming film Suicide Squad was announced. The day before, Grimes announced her contribution to the soundtrack on Twitter. It’s called “Medieval Warfare.” Stream the track, and a conversation between Grimes and Zane Lowe on Beats 1, below. During the interview, she told Lowe, among other things, that she’s “dead serious” about wanting to train for the UFC; she doesn’t hold out hope of actually making the mixed martial arts fighting circuit. Scroll down for the artwork of Grimes as a Suicide Squad skull.

The track follows the Skrillex and Rick Ross collaboration “Purple Lamborghini,” “Standing in the Rain” by the Black Keys’ by Dan Auerbach, Action Bronson, and Mark Ronson, and Kehlani’s “Gangsta.” The soundtrack also features Eminem, Lil Wayne, Wiz Khalifa, Kevin Gates, Imagine Dragons, Ty Dolla $ign, and more. The Suicide Squad soundtrack is out August 5, the same day as the film. It stars Will Smith, Jared Leto as the Joker, Margot Robbie, and more.
