HAIM’s debut album Days Are Gone is nine months old now, and it hasn’t remotely stopped sounding amazing. The album’s biggest curveball remains “My Song 5,” with its gigantic seesawing almost-dubstep electro-bass. And today, there’s a new version of that song, with a verse from Harlem rap livewire A$AP Ferg. The combination makes more sense than you might expect; Ferg, despondent over some relationship or other, sounds absolutely at home on this huge farting thing. Zane Lowe premiered the song today; listen to a radio rip below.

Days Are Gone is out now on Columbia.
