36 - Black Sabbath Heaven and Hell 1980

Classical heavy metal song, it may belongs to the best Sabbath album ever. An incredible strong album that shows both nerve, epic features, attitude, melody and fantastic composed and performed songs. Heaven And Hell has those genius vocal parts in the songs slower parts, not to mention the fantastic bombastic refrain, poetic philosophical lyrics that makes you twist your mind, Iommi's stellar guitar work in the mid-section and the up-tempo ending part with outstanding lead guitar passages.
One of the biggest Metal anthems ever created, every single element making up a genius whole.
