This 1971 heavy metal album by Black Sabbath is my favorite. It has their most known song; "Iron Man". Other songs here are "War Pigs/Luke's Wall", "Paranoid", "Planet Caravan", "Electric Funeral", "Hand of Doom", "Rat Salad", and "Jack the Stripper/Fairies Wear Boots". Paranoid is one of the best and most popular heavy metal albums of all time. A big collection of their music is Black Box: The Complete Original Black Sabbath (1970-1978).
