"Painkiller" follows recently released track "Feet Don’t Fail Me Now Part 2", featuring Ravyn Lenae. The song was produced by Crookes and Dweller, and serves as an homage to 1990s hip-hop as Curry and Crookes come together to explore a destructive relationship.

"I wrote Painkiller years ago after the end of a destructive relationship," Crookes says. "It's a conversational tune where I go through the motions of why I dated such a gobshite. alas, at least I got a nice tune out of it."
