So much this!
Ozzy might be crazy, talentless, poor writer and singer, a crook, a puppet and the Lars Ulrich of heavy metal singers, but he's still fucking Ozzy. Even if you don't like his singing, you can't take him out of the equation. Like, Sabbath isn't Sabbath without him (and as much as I love Dio and the Sabbath records are better with him, etc. etc. etc. the Dio years are a total different thing for me than the Ozzy years).
