Where can I find the bluegrass/banjo-y version of Thus Spoke Zarathustra (aka 2001 A Space Odyssey) that is playing during 4x speed button-finishing section of this video?
I think it may be “Moon Music” - Downloadable from the Glitch website and possibly even used in the game.

P.S. This IS the internet, so just as a general rule, copy/pasting text into the address bar rather than clicking the link is a good idea.
