This has probably been caught plenty of times in different circles, but I have been really fixated on it:
The music reminds me of Bomberman 64, the primitive 3D visuals are very nostalgic. It all works really well together. Digging into the musician behind it, he does actually have some albums up on Spotify, including some new ones!
According to the source himself, there is no extended version of that song, only the length made for that opening. So I guess there you have it, then.
