Though many bands have succeeded in earning the hatred of parents and media worldwide throughout the past few decades, arguably only such acts as Alice Cooper, Judas Priest, and Marilyn Manson have tied the controversial record of Ozzy Osbourne. The former Black Sabbath frontman has been highly criticized over his career, mostly due to rumours denouncing him as a psychopath and Satanist. Despite his reputation, no one could deny that Osbourne has had an immeasurable effect on heavy metal. While he doesn't possess a great voice, he makes up for it with his good ear and dramatic flair. As a showman, his instincts are nearly as impeccable; his live shows have been overwrought spectacles of gore and glitz that have endeared him to adolescents around the world.
