I personally would be so bold as to say that black metal is a modernized form of classical music (new Dimmu Borgir, Cradle of Filth, new Satyricon are not black metal, they're bubblegum hard rock for the record). This stems from the fact that the current "modern classical" (20th/21st century) actually is not defined as music by a majority of music theory professors.
Largely metal has always held the point of rebellion and freedom. In death metal this really rings especially true, as black metal is generally more about art. The bands on the radio, well that's about money, so how would that be classified as music? Grunts/raspy vocals are used more as an instrument to the music, not to deliver a message necessarily. Now you could say that I have contradicted myself by saying this, but the "message" of rebellion and freedom is expressed in musical style. Not playing that generic radio drivel, not being predictable in the motion of the music, not being afraid to try something completely new stylistically.
Metal needing grunts to be metal... How about Sodom, Kreator, Celtic Frost, Bathory, Megadeth, etc...? Then again, I'm just a huge classical fan that also happens to enjoy a lot of metal.
