In your opinion, what is the heaviest song ever?

I thought of early Sabbath, also.

For me it's maybe the eponymous Black Sabbath track.

After much pondering. Black Sabbath - with the bell & rain then the doom hook from Tony Iommi. The heaviest for me too. Ozzy pleading more than singing. Bass in overdrive. The drums plodding and drawn out (sounds like they were recorded in a cavern). Ahhhh, yep that's my definition of heavy.
