If you're having trouble getting into the Halloween spirit, you might check out the Halloween Musical Tricks and Treats playlists [iTMS link] on iTunes. There are 3 Halloween-specific playlists up right now,
The Basics - 25 tracks, featuring Bobby Pickett's Monster Mash, Michael Jackson's Thriller, and Bow Wow Wow's I Want Candy
Next Steps - 24 tracks, featuring Santana's Black Magic Woman, The Doors' People are Strange and Monsters Lead Such Interesting Lives, by Mel Torme, The Velvet Fog himself
Deep Cuts - 24 tracks, featuring Robert Walsh's Amityville Horror, Marilyn Manson's cover of Sweet Dreams (Are Made of This) and Screamin' Jay Hawkins' Whistlin' Past the Graveyard.
Top it off with an episode of The Addams Family, which Scott mentioned last night, and a bucket full of candy corn.
If that all doesn't get you in the mood to give candy to strangers, nothing will.
