ONLY THE HEAVIEST BONE CRUSHING AURAL RAPE, but see if you can explain why it's heavy or something......hold on, i'm still thinking this through

Everyone has a different idea of heavyness. I once tried to argue that "overkill" by Motorhead is the heaviest recording of all time. http://www.youtube.com/watch?v=3VNUyjRRjxM it's hard for me to articulate why. It's just...fuck it's so heavy.

So how do YOU define heavy? And what's the heaviest thing YOU'VE ever heard?

For the record, I think this is the heaviest shit ever. Doesn't really need explanation, harsh vocals, drop G tuning, bassy production.... http://www.youtube.com/watch?v=dZrSjyPrgJk

bonus question: why is heavyness appealing?
