“Out of My Head” was the first taste of Charli XCX’s mixtape POP 2. It premiered on BBC Radio 1 on Wednesday, December 6th, 2017 with POP 2 being released the following week, on December 15th.

This electronic dance-pop track featuring Tove Lo and Alma is about partying to forget your problems. The three singers talk about dancing and doing drugs to distract themselves from a person who hurt them but who they still like and can’t forget.
