Heaviest Song Ever!

Anyone saying Black Sabbath is retarded. lol

That's my OPINION.

Heavy to me means it makes you want to break shit...or like someone took a sledgehammer to your skull.

Lots of heavy/brutal bands out there for sure, but some are better than others due to songwriting, they really know how to pack a whallop instead of just blasting beats.

Cannible Corpse and Behemoth are the heaviest most brutal sounding bands I've heard. CC live in concert was merciless.

congratulations on demonstrating perfectly the attitude that has worked towards corrupting metal ever since its inception. please kill yourself.
 
I'm sorry to say this but on the "what is heavy?" topic, i think anyone who associates speed with heavy is a fucking retard. Compare a sports car and a tank, sports car = fast and light, tank = slow and heavy. I don't get how someone can associate speed with being heavy.

*EDIT*
To Live Is To Die by Metallica is my prime example of heavy since it's basically a concrete sledge to the head.
 
Heavy for me are songs that make me headbang against my will - I've incurred numerous injuries against my desk because of this.

At this moment in time Gojira are denting my forehead. This is an impossible question though.
 
From the genres I listen to:

Mayhem - Freezing Moon
Darkthrone - Quintessence

Among other genres I think any Brutal Death Metal or Grindcore song could be the heaviest ever.
