Thank you. :)
Yes there is. They are both temporary tunes from https://opengameart.org/ and the files are called "stealthsteady_basic" and "taiko-drums". I have been trying to find the direct links on the page, but it somehow doesn't work for me right now :/ I quickly checked the game's credits again to see who made them:
Taiko Drums by jobro with edit by congusbongus
Stealth steady basic by SouljahdeShiva
Maybe you have more luck in finding them right now :)
