So here's the story.
I was hanging around the MBAA OST topic, and lo and behold, I got the chance to hear
Nightmare Teller and geeked out over it.
Sometime later, while I was watching a random video uploaded by a friend of mine, a funny looking thumbnail caught my eye, which lead me to
this video upon clicking it.
Now, while I already know that the latter is a doujin parody game, I'd like to know, assuming Nightmare Teller was made especially for MBAA and wasn't in any other MB game before it, how this game was able to contain a parody/remix of it some two or more years before AA was released.
Or, failing that, I'd like to know what song Nightmare Teller and that other song are remixes of.
Your help is greatly appreciated, as this has been gnawing at my mind for the past week or two and I fear losing what's left my sanity soon.
