Pop 2 was the second mixtape Charli XCX released in 2017, originally issued in December of that year. A. G. Cook was executive producer and pushed the PC Music sound to its limits: warped vocals, cutting synths and abrupt transitions, a sound later filed under hyperpop. Almost every track has a guest, from Carly Rae Jepsen on Backseat and Caroline Polachek on Tears to Tove Lo, ALMA, Kim Petras, Jay Park, Dorian Electra, Mykki Blanco, CupcakKe, Brooke Candy, Pabllo Vittar, Tommy Cash and MØ on Porsche. Closing track Track 10 was reworked two years later into Blame It on Your Love with Lizzo.

This edition is an LP on translucent purple vinyl, released as a fifth-anniversary edition with a poster.
