What's your favorite Halloween song?

I don't mean "what's your favorite Halloween song," and I definitely don't mean "what's your favorite John Carpenter song," but more what's your favorite "Halloween-appropriate" song? Something like one of these, or any of these, if that makes any sense.

There are some great Halloween-centric songs out there that I don't know squat about, but want to. If you can point me in the right direction, please do!
