The New Moon soundtrack is the official music for the 2009 film New Moon. The score for New Moon was composed by Alexandre Desplat while the rest of the soundtrack was chosen by music supervisor Alexandra Patsavas, who also produced the Twilight soundtrack. The New Moon: Original Motion Picture Soundtrack album was released on October 16, 2009 by Patsavas' Chop Shop label, in conjunction with Atlantic Records.
New Moon's soundtrack comprises songs that are all original and exclusive to the soundtrack and are performed by various indie rock and alternative rock artists. New Moon director Chris Weitz stated that the soundtrack would feature songs from Radiohead, Muse, and Band of Skulls. Death Cab for Cutie contributed the soundtrack's lead single, a song written specifically for the film called "Meet Me on the Equinox", which debuted September 13 during the MTV Video Music Awards. Bassist Nick Harmer says, "We wrote 'Meet Me On the Equinox' to reflect the celestial themes and motifs that run throughout the Twilight series and we wanted to capture that desperate feeling of endings and beginnings that so strongly affect the main characters." The music video for "Meet Me on the Equinox" premiered on October 7, 2009 and includes clips from the movie. The English rock band Muse contributed a remix of their song "I Belong to You", which appears in its original form on their 2009 album The Resistance. St. Vincent collaborated with Bon Iver's Justin Vernon to create a song called "Rosyln". When describing the song, she said, "[Justin] sings in his beautiful falsetto and I'm actually singing very, very low... I think there's something vampirey and creepy about the two of us singing together. It's a simple, stripped-down kind of song." The soundtrack originally had a release date of October 20, 2009, but the date was moved up four days to October 16 due to "overwhelming and unprecedented demand". .
