How are your plans for Halloween shaping up? For me, the hardest part of throwing a Halloween party is choosing a soundtrack. We can probably all agree that those sound effect CDs — the ones with creaking doors and thunder and maniacal laughter — have no business outside of an elementary school haunted house, but then what? Do you put together a playlist of all the obvious soundtrack selections? Do you choose pop songs that have some vague tie-in to the season? Who really wants to hear Warren Zevon’s “Werewolves of London” on Halloween for the umpteenth time, anyways?
