At Metacritic, which assigns a normalised rating out of 100 to reviews from mainstream critics, Number 1 Angel received an average score of 73, based on 5 reviews, indicating generally favorable reviews. Frank Falisi from Tiny Mix Tapes gave the mixtape four out of five stars, comparing it to Madonna's early works and calling it "a text for mitigating engagements." At Pretty Much Amazing, Mick Jacobs stated that "Aitchison intelligently pairs her clever lyrics against beats that push genres outward, her filling in the spaces with her hooks and gigantic personality," whilst Katherine St. Asaph of Pitchfork wrote that the mixtape "is largely stolen by its guests, like Uffie and CupcakKe."
Pop 2 is the fourth mixtape by English singer and songwriter Charli XCX, released on 15 December 2017 by Asylum Records. Executive produced by A.G. Cook of PC Music, sessions for the mixtape began just several months before its release and featured a wide variety of guest contributions. The project received praise from music critics, and was backed by the single "Out of My Head" featuring Alma and Tove Lo.
At review aggregate site Metacritic, Pop 2 has an average score of 84 out of 100, based on 8 reviews, indicating "universal acclaim". Meaghan Garvey of Pitchfork called it "the best full-length work of both Charli and PC Music’s respective careers," opining that "though Pop 2 sounds like the future, even more delightful is the way it hybridizes sounds from the past two decades of weirdo electronics." Ludovic Hunter-Tilney of Financial Times wrote that Charli XCX "stands out as a paragon of progressiveness," opining that "on the majority of the tracks Charli and her producer Cook deploy their meta-pop tactics with a skilful sense of dramatic engagement."
