Even Mike WiLL Made-It’s hardest trap beats have a watery feel, like you just woke up on the sticky floor of a raging club as the song begins. But the Atlanta duo Rae Sremmurd’s “Black Beatles” sounds like two different Super Nintendo water levels playing on separate browser tabs; it starts out submerged and never surfaces. The songs’ two synth patterns, running in opposite directions, are transfixing, and listening to them is like staring dumbly at the light ripples at the bottom of a backyard pool after taking a too-generous hit.

By now it’s clearer than ever that Rae Sremmurd are Mike WiLL’s muses, the artists that he was designed to work with. Together they have Just Blaze/Jay chemistry, Waka Flocka Flame/Lex Luger chemistry. Swae Lee and Slim Jxmmi rap and sing entirely in punchy, candy-shelled couplets that conceal razors: “She think she love me/I think she trolling”; “quick release the cash, watch out for slow leaking”; “get you somebody who can do both.” There is not a single second of this song you can touch without getting it stuck to you. The ad-libs are hooks, the verses are hooks, the hooks are hooks. Gucci Mane’s clone wanders through, too, and while he sounds great, he also sounds relatively conventional here, the adult crashing the kids’ party.
