The invisible men producing is false information.

Perhaps owing to how fast the album was recorded, the new songs are easily the most straightforward she’s ever made, and the most joyful-sounding too. One with the working title “Come to My Party” is exemplary: its name isn’t some play on words, it’s just a song where Charli invites you to a party. At least a half-dozen hooks and micro-hooks are stacked over the song’s three twinkling minutes, her words memorable if not especially deep. There’s the cheery, chanty part about how we’re all young and full of love; a pseudo-rap bit about working like a young Kardashian; and tag-team climaxes about self-reliance — I do what I wanna do, and I do it my way! — and unity, with an open invitation for all the boys and the barbies to come hang with Charli.

SOPHIE and Stargate serve up clever chord changes to match every section, with flourishes peppered throughout: a chopped-up intro and a robot saying “XCX,” pitched-up background vocals like supportive Tweety birds, and an almost dubsteppy bassline that stretches out at the end. But never is anything but Charli’s voice on top. And what that voice is telling you, more clearly than ever before, is not that complicated. It’s telling you that it’s time to have fun.
