This particular song, I didn't really enjoy working with. There's a bit of a subtlety that I suspect I lack, because I can't really get into pieces that have extended amounts of silence. It feels sort of off-putting and makes it hard for me to work on. I did my best to re-create the original piece, and left it at that.
The song normally pops up when you encounter a non-enemy, usually a skeleton or zombie or doll or the like, that gives you some sort of hint or cryptic message.
