Thanks for mentioning that, had me digging around for where I can find the music. The youtube link lead me to the project's hackaday log, which is extremely detailed but lacks any mention of music [0]

The submission link's github page [1] links to a website listing all the tracks that ever played [2], explaining they dropped the music from the project so as not to deal with copyright claims. too bad fair use isn't clear enough to apply here, I think its a relatively transformative use and doesn't compete with the original.
