This was a super fun one! What other songs/artists would you pick?? :_fart:

The heaviest non metal is Iodine, hope that helped.

The Prodigy were an electronic act so heavy they were uniformly accepted by the metal community. Fundamentally they're a dance act but they popped up at a bunch of heavy festivals and always went down a storm.

Look, the heaviest non-metal song ever is Toccata and Fugue in D Minor by Johann Sebastian Bach. To this day, it's still the default spooky, monster, Dracula-ass theme song. That shit goes hard.

The Thomas the tank engine theme has no business going as hard as it does

You missed the genre that surpasses metal in harshness: noise.

Another good heavy classical moment is In The Hall of the Mountain King from Peer Gynt. Starts off slow and quiet, builds to an utter moshpit, largely because it's supposed to represent a bunch of angry Trolls hurling boulders at the hero.

If you didn’t mention classical music I would’ve rioted

O Fortuna will always be one of the heaviest intense ominous dramatic epic pieces of music

3:25 Bradley realizes he's just briefly headbanged to Nickelback and has to right his course

Throbbing Gristle, Dead Kennedys or any of the 70's British Industrial bands were usually heavy enough to exceed their Schwarzschild radius and cause a black hole event.

The outro of The Beatles’s “I Want You (She’s So Heavy)” is straight up Doom Metal, like WTF IT’S SO HEAVY

The heaviest non metal song has to be "I Put A Spell On You" by Screamin J Hawkins

The End - The doors get super intense and heavy

"In the Hall of the Mountain King" by Edvard Grieg is a true metal masterpiece.

4th of July by Soundgarden, the riff sounds like something I could hear in a crowbar song. hearing chugging on such a low tuned guitar with heavy distortion and gain on a non metal song confused the hell out of me but it's a fantastic song, I love how bands like Alice in chains and Soundgarden were always pushing the boundaries of that blurry line between grunge and metal.

I have to say Lizzo is probably the heaviest non metal artist

Hash Pipe by Weezer deserves a mention, that riff goes so hard

Fun Fact: When Stravinski debuted Rite of Spring, the audience were so outraged by how heavy it sounded, they rioted and tore the place apart!
