Deadpool 2

Deadpool composer Junkie XL chose not to return for the sequel due to Tim Miller's departure. In October 2017, Tyler Bates was hired to write the score for the film. The 12-track soundtrack for the film was released on May 18, 2018, including two singles: "Ashes" by Céline Dion and "Welcome to the Party" by Diplo, French Montana and Lil Pump. Dion's "Ashes" was released as the lead single on May 3, 2018, along with a music video of the vocalist singing the song, and Deadpool dancing an interpretive dance beside her. Following the completion of the song, the titular hero proceeds to critique her singing as being 'too good' for a Deadpool movie. "Welcome to the Party" was released as the second single on May 15, 2018. The song "We Belong" by Pat Benatar was used in the film to illustrate the theme of family that the writers were exploring, and was almost used a second time during the X-Force parachuting sequence but was replaced with AC/DC's "Thunderstruck" which was used as a "pump me up" song—because of its "straight" tone and use in Iron Man 2—to help sell the excitement of the audience before the X-Force characters are unexpectedly killed. Bates felt his role was to mostly stay out of the way of the film's comedy and instead support the action and emotional elements, and he had to pace his music to line-up with the fast-paced nature of the dialogue and jokes. He descirbed the film as a "a true Rubik's Cube" to score because of all the different elements involved, and approached the music with a slight rock sensibility. Specific instrumentation that Bates used for the score included a distorted guitar run through a wah-wah pedal, microsynths to add "unique colors", and a choir that sings "some things that you probably aren’t expecting" for a comedic moment.
