Charli XCX Continues to Reinvigorate the Remix Thanks to "Guess" with Billie Eilish

While Charli's cheeky, suggestive rap invites the listener to "guess the colour of my underwear," Billie makes it clear that she knows exactly what colour said underwear are. "Charli likes boys, but she knows I'd hit it / Charli call me it you're with it," Eilish invites, clearly getting the memo that every BRAT lyric should be as blunt as possible.

While the original version of "Guess" pushed the limits of my tolerance for just how trashy a dance track can be while still being enjoyable, Billie's appearance is a "holy shit did she just say what I think she said" moment — the kind of jaw-dropper that, these days, is usually reserved for Kendrick Lamar guest verses. As soon as it was done, I texted at least three people to ask them if they'd heard it yet. I don't remember the last time a song made me do that.

It seems that reports of BRAT summer's death have been greatly exaggerated.
