Released by Canadian Indie Rock band Metric in 2006 as the first single off their third album, "Monster Hospital" is a riff-heavy but danceable track sure to get your ghastly guests moving and grooving. Lead singer Emily Haines' light, echo-y vocals balance out the fast-paced instrumentals and create a searingly spectral track fitting for the season. (Warning: Easy-spookers may want to cover their eyes before pressing play, as this music video is practically a horror movie unto itself!)
