Charli XCX featuring Billie Eilish, ‘Guess’

In the slightly less than two months since its release, Charli XCX’s sixth album, “Brat,” has transformed from a clubby cult classic into a mainstream phenomenon, fueled by a sense of cool so elusive yet galactically powerful that a CNN panel recently convened to discuss, with magnificent awkwardness, its potential impact on the presidential election. Strange times indeed. Luckily, Charli is still keeping it light, not allowing the new patina of Importance to cloud the fact that “Brat Summer” is, above all things, about messy, hedonistic fun. So let’s just say that the latest “Brat”-era remix, the deliriously suggestive “Guess,” is unlikely to appear in an upcoming Kamala Harris campaign ad.

“You wanna guess the color of my underwear,” Charli winks atop an electroclash beat produced by the indie-sleaze revivalist the Dare, who interpolates Daft Punk’s 2005 single “Technologic”; Dylan Brady of 100 gecs also has a writing credit. It’s an underground loft party crashed by a bona fide A-lister: Billie Eilish, making her first guest appearance on another artist’s song, purring a playfully flirtatious verse that ends, “Charli likes boys but she knows I’d hit it.” It’s refreshing to once again hear Eilish on a beat as dark and abrasive as those on her debut album, but she and her brother and collaborator Finneas know they are ultimately on Charli’s turf, reverently endorsing the trashy aesthetic and if-you-know-you-know humor of “Brat.” “You wanna guess if we’re serious about this song,” Charli intones at the end, as Eilish lets out a conspiratorial giggle. Against all odds, reports of Brat Summer’s death seem to have been slightly exaggerated. LINDSAY ZOLADZ

Okaidja Afroso, ‘Kasoa’

Okaidja Afroso, from Ghana, sings about cycles of nature and human life in his childhood language, Gãdangmé, on his new album, “Àbòr Édiń.” But his music exults in modern technology and cultural fusions. The six-beat handclaps and bass riffs of “Kasoa” look toward Moroccan gnawa music, while the vocal harmonies exult in computerized multitracking. “There will be meetings and partings, and joys and sorrows,” he sings. “May we journey with ease, and hope to cross paths again in another lifetime.” JON PARELES
