With Halloween coming up on Wednesday, we decided to move our usual weekly question to Monday to prepare a horrifying poll for the big day.What is the scariest music video ever?They don't have to be frightening videos, but it'll help if they fit the spooky Halloween theme.Maybe you'll opt for something theatrical by Rob Zombie or Marylin Manson, or something so old and bad that's it's good. Like an old Ozzy Osbourne video. There's some wonderfully dark conceptual videos by the likes of Tool or The Knife worth considering. Or, if you want to step outside the rock realm, there's some crazy videos by electronic artists like Aphex Twin which could give anyone the creeps.Place your nominations in the comments, and remember to upvote the posts you agree with. Feel free to add a YouTube link so your fellow readers can see the clip before voting.We'll stack up the results and post them in a special Halloween list on Wednesday, alongside a tonne of other festive features. Thanks!
