Which song by Brad Paisley and Robbie Williams plays over the ending credits of Pixar's Cars 2?

“Collision of Worlds” plays over the ending credits of Pixar's Cars 2. The song was performed by Brad Paisley and Robbie Williams and reflects the film's meeting of American racing culture with international spy adventure.

Paisley also contributed other music to the Cars franchise and is strongly associated with the series' country-influenced sound. Robbie Williams brought a British pop perspective that suited the film's international setting and its British spy character, Finn McMissile.

The Cars 2 soundtrack includes original score by Michael Giacchino, along with songs connected to the film's locations and characters. “Collision of Worlds” is not the same song as “Find My Way,” which is associated with Cars 3, or “Our Town,” which Randy Newman wrote for the original Cars.

The title itself summarizes the movie's premise: Lightning McQueen enters a worldwide race while becoming involved in an international espionage plot. That blend of racing and spy-film conventions is what distinguishes Cars 2 from the other two main films.
