Alkaline Trio - Over At The Frankenstein Place.

Marilyn Manson - This Is Halloween.

Oingo Boingo - Dead Man's Party.

And of course, Jack's Lament.

Also, just about anything by Voltaire:

The Headless Waltz.

Brains. - This would be awesome to play on your porch. (It's from The Grim Adventures of Billy and Mandy.)

Reggae Mortis.

Day of the Dead.

Dead and Zombie Prostitute may not be entirely appropriate, but they're still good songs.

Can you tell I'm a fan?
