The propulsive electropop track was produced by A.G. Cook and Life Sim. Charli XCX met both German singer Petras and the Korean-American hip hop artist Park recently, and recounts how she began collaborating with them in a Beats 1 interview with Zane Lowe.
This is the second time she’s worked with Park, who recently signed with Roc Nation, and who XCX praises for being a huge star in South Korea. He appeared in her music video for “Boys,” released in July.
In the same interview, XCX describes the mixtape as being “about everybody having their moment to shine.” Along with Alma, Park, Petras, and Tove Lo, Pop 2 will also feature Carly Rae Jepsen, Caroline Polachek, Brooke Candy, CupcaKKe, Pabllo Vittar, Dorian Electra, Mykki Blanco, Tommy Cash, and MØ. The mixtape will be released on Dec. 15.
Along with releasing “Unlock It” on music sites and streaming services, the new song was released on YouTube through an official audio video. Listen to it here:
