Good! I love the creepy humming and ambiance of the tune! It sounds like it would work really well in a cave themed game, like the pops in the background sound like water droplets. Or, it can also work really well in like a ghost/paranormal activity game, in something like a haunted tower, or in a zombie apocalypse game. Really good! My problem is that the humming in the background - that sort of whistle thing - gets really loud at parts and hurts my ears. Overall, good work, but needs a small bit of improvement. :)
