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.[2] 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.
Jeff Williams intended "hiring some badass soprano opera singer" for the Italian singing, but the test track by his daughter Casey Lee Williams impressed him so much he kept it, as well as bringing Casey to record the chorus of Falling Towards the Sky.
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.
