2015–present: Label problems and PC Music collaborations
In a July 2015 interview, Charli XCX said that she was working on her third album and described it as "the most pop thing, and the most electronic thing" she had ever done. Scottish producer SOPHIE, along with BloodPop and Stargate, was confirmed to be involved in the album's production. In October 2015, she premiered new song "Vroom Vroom" on the Beats 1 Radio Show, then claiming it would be the first song released from her third studio album. On 23 February 2016, it was announced that she had set up a new experimental pop record label, Vroom Vroom Recordings, and that she would release an EP titled Vroom Vroom on 26 February 2016. The title song was officially released that day. The second song released from the EP, titled "Trophy", received its first play on Zane Lowe's Beats 1 show on that night. It was also announced that she would also host her own Beats 1 show fortnightly. It was produced mainly by SOPHIE as a teaser for her third studio album.
