Black Sabbath frontman Ozzy Osbourne died following his battle with a genetic form of Parkinson's disease, while a brain expert says the singer's lifestyle could have contributed.

Heavy metal legend Ozzy Osbourne dies at 76. The Grammy-winning Prince of Darkness long struggled with addiction, finally achieving sobriety in 2014.

After selling millions upon millions of albums with Black Sabbath and his solo projects as well as benefiting from Ozzfest proceeds, Osbourne was in a better place financially than he could have ever imagined back in his cow-killer days, but life remained a challenge. Instead of post-industrial decay holding him back, this time it was all him.

Meanwhile, Ozzy’s oldest daughter, Aimée Osbourne is worth an estimated $7 million. His other daughter, Kelly Osbourne, had an estimated net worth of $16 million, and his son, Jack Osbourne, has an estimated net worth of $15 million, according to the site. So, again, it appears that the “Prince of Darkness” left his family in a blessed situation.
