Recurrent Pixar composer Michael Giacchino was announced to compose the score for the film, marking his eighth collaboration with Pixar and the second time he would score an installment to a film franchise from Pixar that is traditionally scored by Randy Newman, after Cars 2. He earlier scored for the Toy Story television specials: Toy Story of Terror! (2013) and Toy Story That Time Forgot (2014), the former was written and directed by Maclane. The score was recorded over 15 days, requiring a 39-member choir and an 89-piece orchestra. A track titled "Mission Perpetual" was released as a single on June 3, 2022. Giacchino said the track was his favorite to work on the film, describing it as a challenge due to the music needing to convey Buzz' frustration, sadness, and determination through the sequence. The soundtrack will be released on June 17, 2022 through Walt Disney Records.
