There's not too many definitive Halloween anthems, so when Tim Burton released The Nightmare Before Christmas his twisted Christmas songs became spooky Halloween classics. Although the film is filled with top-tier songs (our personal favorite is "What's This?"), "This is Halloween" is the most ghoulish of them all. Sort of like a "Deck the Halls" for the eeriest time of the year, "This is Halloween" makes note of all the essential Halloween ornaments and rituals. With the pumpkin song, spiders, and werewolves, you'll be in the Halloween spirit instantly after playing this tune.
