I think that is being a little obtuse. Ozzy/Black Sabbath made heavy metal. Hulk Hogan created a persona and kept mainstream wrestling relevant when it was dying. He kept the WWF/WWE alive. They are both masters of their respective craft.Ozzy created art that transcends generations and race, his music will still be relevant a decade from now and maybe even a century from now. Hogan will be forgotten as soon as he reaches room temperature.
