This is all of the original music from The Roottrees are Dead and Roottreemania. It includes Investigative Jazz heard on the in-game radio as well as all of the "in-universe" songs created by the members of the Roottree family.

If you're wondering why a song you've heard in-game isn't on this soundtrack, it is because it was not made for The Roottrees are Dead. In addition to our original songs we used many free songs that have generously made their music available to us and other developers. When one of those songs is playing, you can open the cassette tape icon and follow the link there to find the artist's website for more information about how you can add it to your collection.
