Over at the Woot! blog, they've got a mixtape made up of YouTube videos for Halloween. It's "a bunch of really cool songs with monsters in them which never ever get played on the radio."
More than just "Monster Mash," there's tunes from Oingo Boingo and the Guess Who. Never thought I'd see those acts next to each other, but there you go. Enjoy this version of "Monster Mash" as done by Bad Manners, and have a happy Halloween.
