Heaviest Metal Songs of the 70s

Things change:
1) These songs don't sound heavy now but they were heavy in the 70s.
2) Some of these songs weren't considered metal (or related to metal) in the 70s but history proved it wrong.
3) Some other songs that aren't on this lists were considered metal (or related to metal) in the 70s but now we know they aren't metal songs.

Keep in mind that these bands are related to early metal but not all songs by them are metal.
The Top Ten
1 Kill the King - Rainbow

I think it's the heaviest because it's the most aggressive song of the 70s, one of fastest and one of the loudest.

2 Dissident Aggressor - Judas Priest

A pretty brutal song for 1978, particularly the riff.

3 A Light in the Black - Rainbow

A 1976 metal masterpiece - fast, aggressive, technical and epic. Unlike most of the songs on this list, this song is 100% metal and has no poppy, bluesy and whatever parts different from metal.

4 The Wall - Squadron
5 Stone Cold Crazy - Queen

A proto-thrash song. It has some very fast and aggressive parts, with thrashy aggressive vocals, but also some poppy sections.
Nobody considered it related to metal in the 70s because thrash didn't exist.

Yes, Queen had heavier songs in their earlier albums. Ogre Battle is also heavy.

This is hard even in 2020, but the heaviest Queen song is The Hitman, that song is heavy

6 Hard Lovin' Man - Deep Purple
7 Children of the Grave - Black Sabbath

Heavy as F!
Vote for this, for god sake
Just admit it this is the heaviest song in 70s

8 Ride the Sky - Lucifer's Friend
9 Black Sabbath - Black Sabbath

Not very high on this list because it's very dark but not very heavy in the strict sense.

This song IS heavy metal.

10 Burn - Deep Purple
The Contenders
11 Sweet F.A. - The Sweet
12 Symptom of the Universe - Black Sabbath

This is the undisputed heaviest song of the 70s no doubt. It was thrash a decade before thrash was invented.

13 Set Me Free - Sweet
14 Tyrant - Judas Priest
15 Exciter - Judas Priest
16 Into the Void - Black Sabbath
17 Electric Funeral - Black Sabbath
18 Stained Class - Judas Priest
19 Under the Sun - Black Sabbath
20 Sabbath Bloody Sabbath - Black Sabbath

This song heavy? LOL. Just play the sample guys...It sounds like a pop song compared to Kill the King by Rainbow. And even compared to Stone Cold Crazy by Queen.

21 Free 'N' Easy - Uriah Heep
