All of the music in RunMan: Race Around the World comes from the public domain. It is a unique blend of folk, blues, jazz, and other styles of music from a wide array of artists and times. Below, some examples.
The game's soundtrack can be listened to in full - just browse the oggs folder.
Big ups to Public Domain 4U and archive.org for making these groovy songs so easy to find.
