The Red vs. Blue: Season 9 Soundtrack contains music from Season 9 of Red vs. Blue. The music is composed by Jeff Williams and features members of the cast. It also features other artists such as: Casey Williams, Sandy Lee Casey, and Lamar Hall. The soundtrack is currently available on iTunes, Google Play, Amazon, and Spotify.
This is the second Red vs. Blue soundtrack to feature songs containing lyrics in a language other than English. In this case, the song Extraction utilizes Italian lyrics. The song Hell's Angel reprises a snippet of the song Plagam Extremam Infligere from the Red vs. Blue: Revelation Soundtrack, which utilizes Latin lyrics.
The songs Pelican Reveal and Crazy Carolina are not present on the album; instead, they were released for free by Jeff Williams on Rooster Teeth's forums. In addition, the song Such a Bitch is combined with Immersion as a hidden track.
Despite the fact that it appears on the Season 9 soundtrack, Donut: The Musical wasn't used until Season 13, and even then it was a five second appearance in one of the PSAs.
