Robin Hilton describes the album as ‘future pop’s:
Charli XCX makes wildly warped, genre-bending songs that are artful and adventurous but can still top the charts. On the English singer’s latest album, Charli, she collaborates with Troye Sivan, Lizzo, Haim and more for a sound that moves pop firmly into the future.(source)
While Debbie Carr suggests:
Charli may be laced with all the screeches and squelches of everyday life in one giant sensory overload, but at its core the album is a snapshot of the experimental era pop is moving into.(source)
For me, this album has the feel of speculative pop. It is true that many of the elements of pop are still present. However, the speculation comes in the way of form and production.
