Music that scares you (even if it shouldn't)

When I was a kid, I was so unnerved by the Who Wants to Be a Millionaire music. I would be walking up the stairs at night and hear the ominous background music playing softly in my head. Needless to say, I'd start running up the stairs. Well I recently went back to listen to just the music and holy crap it's even scarier than I remember:

Then the final rounds are even worse:

Am I crazy? Is that not flat out terrifying? I know Halloween is long over but I didn't expect the repressed Who Wants to Be a Millionaire memories to come back into my life like a psychotic ex-girlfriend. Any music in particular that gives you guys the creeps? Let's all get our demons out there and be scared (or not scared) together.
