As with its predecessor, many tracks by external musicians are featured in the movie, its closing credits, and the soundtrack album, some of which were written for the film. Many of the musicians featured, for example Rob Zombie, Rage Against the Machine and Marilyn Manson, had also appeared on the soundtrack for "The Matrix". Rob Dougan also re-contributed, licensing the instrumental version of "Furious Angels", as well as being commissioned to provide an original track, ultimately scoring the battle in the Merovingian's chateau. A remixed version of "Slap It" by electronic artist Fluke — listed on the soundtrack as "Zion" — was used during the rave scene.
