Feast your ears, my eight bit Comrade!
Rejoice in the splendor of the Korobeiniki! Or, Korobushka if you prefer. Either way, you have done a fantastic job with this. The only musical criticism I have is that I would prefer it if your percussion sounded a bit less metallic, but I think that may just be a personal preference. As for it being a Russian folk tune, isn't it supposed to start off slow, and gradually speed up? It still sounds fantastic though.
