Cars 2 is
John Lasseter's only film not to be scored by his frequent collaborator
Randy Newman, who also scored the predecessor. In October 2010,
Michael Giacchino was hired to score music for the film, after previously working on
Pixar's
The Incredibles (2004),
Ratatouille (2007) and
Up (2009). He initially liked the music of the first film scored by Newman, and whenever he watched the film he felt that "he was in the middle of something important or big or something adventurous" and seeing the film, he felt it as a perfect fit. On watching several iterations of the final edit, he said "I've watched the film go through different phases, you know it changes, it evolves. you go through several versions of it to try and get to the best possible version of the story. So I've seen like four iterations of it as it goes." The score had international flavors as most of it does center around Finn McMissile (
Michael Caine), and the music echoes of Radiator Springs and other elements from the first film he did not want to lose. He admitted that there is a thematic element to the film that does develop as the film progresses. Especially to match McMissile's character, a successful spy in the 1960s in London, and he thought of the kind of music he listened for the film, which was surf music that became the centrepiece of the film as well as his identity. On the racing sequences, it had more showcasing racing and no guitar used in the film, if being used it is a combination of the "racing and something else is going on story-wise. So it all depends on what's happening with the story, how much or how little you use of that element." He said that the score is really that surf thing, at its core and had elements such as "fun, action, emotion and friendship" which he liked, saying "You know with these movies, especially at Pixar, the core of the film is usually something very emotional and something that feels really real that you can relate to, it's not like done in a false way. You know a lot of films will treat emotion falsely and you can sense that very quickly, but these films have a way of pulling you in and making you care about these characters because they're treating them like real people, not like a cartoon or something to make fun of, they actually treat them as if they're real people, and I think that's great." As the film featured several cars, he did not want the music to be too overt with the film as it becomes more about the music than it does about the film, as he felt that he want the music to follow the characters.
The Newsboys song “City to City” was featured in the film albeit not credited in the soundtrack. == Track listing ==
