Along with “Blizzard of Ozz,” the album that bore this title track is Osbourne’s best seller. The single, meanwhile, is ushered in with a gripping bass line and an undercurrent of keyboards until Osbourne makes his grand vocal entrance, all sneers and snarls.

Also known as the "Prince of Darkness," Osbourne took the world by storm alongside his Black Sabbath bandmates in the early 1970s, blazing a trail for heavy metal music to ride on.
