Number 1 Angel

In January 2017, Charli XCX stated in an interview with Rolling Stone that she was planning to release a mixtape before the release of her third album[7] saying: "I just got bored and made a load of songs, so I decided to put them out."[8] In another interview, with 93.3, she told the radio station that she recorded the mixtape in two weeks. She described it by saying, "this is more like crying into the champagne than drinking it", and compared it to her work with Sophie.[9] The mixtape was slated for a February 2017 release[9] but was pushed back due to label conflicts. Charli XCX initially recorded the mixtape without her label's permission, stating that the situation, along with the album delay, had her feeling "frustrated and annoyed".[10]
