Through summoning demons from the depths of hell as the frontman of metal pioneers Black Sabbath in their best days, partying hard through the '80s and landing on a reality show focusing on his dysfunctional family in the 2000s, Ozzy Osbourne has kept on the wicked side for the majority of his decades-spanning career in evil. Starting his solo bid almost immediately after his departure from Sabbath, Ozzy turned in classic metal albums with early-'80s Randy Rhoads collaborations like Blizzard of Ozz and Diary of a Madman, and stayed consistently strong with many platinum-selling albums throughout the '90s, 2000s, and beyond.
