I would have to agree with the darkmagnus. In it's day it was Heavy Metal and since Ozzy continues to put out new stuff (although it doesn't really compare to newer metal) it should have it's place in the metal section. Sorta the grandfathers of Metal thing. Just my two pennies
They have so many different variations on metal these days: Death Metal, Thrash Metal, Progressive Metal. . .why don't they just make a Classic metal category. Rock has one!
To me they are all just BMG categories!!
