I don't recognize it. I might have figured out that it was reversed, or maybe not. There's only a few places that sound like they are reverse audio.

I was going to capture it but couldn't figure out how.... so I can't reverse it to unlock the magic .... oh well.

It's actually pretty cool sounding. The only thing is that the melody line.... that flute sounding thing..... if it's the original melody to the song, if reversed would give it away.... then your simple solution is to delete that midi track and create your own. It becomes totally unidentifiable at that point I would assume.

Add nothing that adds nothing to the music.

As the sword chooses the warrior, so too, the song chooses the writer.
