Black Sabbath- Symptom of the Universe  
Would be one of my candidates for 'Greatest Song in History'
...it's just got 
everything...  one of the greatest, heaviest, iconic metal riffs in history (if not 
the greatest)...  fabulous upbeat way-out lyrics (hail Geezer!)  ...a cool energised slick Iommi solo...  that breaks into the most mellow, romantic section ever...  with cool acoustic ending...   
 
 
But it's not just a great song...  it was also part of the groundbreaking formation of metal...  in 1975 there was just nothing else like it...  imagine, this was a band on their 
sixth album producing metal history, before anyone else had even really got to grips with producing metal at all...
NP:   
Black Sabbath - Symptom Of The Universe
