"The Life Aquatic With Steve Zissou" (2004)
"The Life Aquatic" had the most complete soundtrack-to-film ratio of any of the director's films to date -- thanks to Seu Jorge's extra David Bowie covers being released on the 2005 record The Life Aquatic Studio Sessions Featuring Seu Jorge. However, Sigur Ros's "Staralfur," which scores the emotional climax, has never been included on any release.
The trailer for the film was scored in part by New Order's "Ceremony," but the track doesn't feature in the film. As for the music of Sven Libaek, the director was introduced to the composer by actor Noah Taylor (Libaek had written the music for a 1974 oceanographic film called "Inner Space" narrated by William Shatner). Anderson and music supervisor Randall Poster picked up the rights to Libaek's entire body of work, and used them as some of Taylor's character's compositions in the film-within-the-film (Mark Mothersbaugh contributed the rest).
"The Darjeeling Limited" (2007)
The first Wes Anderson film to go without a score, instead mostly utilizing songs found in the films of the great Indian filmmaking auteur Satyajit Ray (with many of the cuts composed by the multi-talented Ray himself). Almost every bit of music from the film was included on the soundtrack for "The Darjeeling Limited." Key missing tracks include Debussy's wonderfully melancholy "Clair de Lune (Suite Bergamasque)," Beethoven's "Symphony No. 7 in A, Op. 92" (used in the flashback on-the-way-to-the-funeral scene), and a few Ravi Shankar tracks. It's not 100% clear what they are, but it apppears to be the title music recycled from Ray's "Aparajito" and "Apur Sansar." It also marks the first time that Mark Mothersbaugh didn't work on one of Anderson's films (the composer returns to the fold with a contribution to "Moonrise Kingdom"), and the first time that The Rolling Stones actually ended up on the soundtrack.
"Fantastic Mr. Fox" (2009)
Again the music of "Fantastic Mr. Fox" is well represented, in part because Alexandre Desplat's score got a separate release on a second disc after the initial soundtrack. But there is one notable absence: the third Beach Boys song to feature in the film, "I Get Around," isn't on the OST.
