Oh my god. This song is so creepy that I just can't find the word to describe it... those unclear voice snippets alone give me the creeps, but this very quiet humming in the background is the icing on top of the "creepy cake", heh.
When the music sets in after a while, the song becomes a tad bit less creepy, so I thank you for that... ^^ But sadly (or maybe, luckily?) the song falls back to it's old, minimalistic style after only a short while.
Long story short: This is a great submission!
