The Top Ten
I think it's the heaviest because it's the most aggressive song of the 70s, one of fastest and one of the loudest. - Metal_Treasure
A pretty brutal song for 1978, particularly the riff. - Metal_Treasure
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. - Metal_Treasure
Yes, Queen had heavier songs in their earlier albums. Ogre Battle is also heavy. - zxm
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. - Metal_Treasure
Not very high on this list because it's very dark but not very heavy in the strict sense. - Metal_Treasure
