I've seen a lot of "guess which game is this song from" threads around and I decided to give this meme a little spin with a song that's not from any videogame (that I know of).
There's a hint included in the FTM, and I'll give you another one just for kicks: The author of this piece has had (a fragment from) another of his songs made famous while played through a sound chip. VERY famous.
Also yeah... I tried the fastest fade-out possible but it popped quite nastily (something it only does in VRC6... though I didn't check if the NSF would have it), so I decided to make it a little bit subtler. Which in the end turned out sounding very vague. Well, at least I tried.
