It always amazes me how touchy people are about genres. I joined VampireFreaks about a month ago, and in just my first browsing of the music forum (before I'd even posted) I came across about countless disagreements and debates about whether a band was considered industrial, or whether a band was gothic, or whether a band was metal, or whether a band was black metal, or how emo music isn't actually emo...it just irritates me to no end. Genres exist as an adjective to make it easier to give an idea about what kind of sound a band has, not to completely define everything a band is. Who gives a s**t if a band fits into a lot of genres and it's easier to just say one of them? People act so elitist. "Marilyn Manson isn't industrial!" "Marilyn Manson isn't gothic!" "It's an oversimplification to call him rock." "Dimmu Borgir isn't black metal!" "Cradle of Filth isn't black metal!" "Cradle of Filth isn't gothic!" "Cradle of Filth isn't metal!" "MSI isn't punk!" "My Chemical Romance isn't emo! All the emo bands were in the 70's!" "Ministry isn't metal, they're industrial!" "Ministry isn't industrial, they're metal!" "System of a Down isn't hyper metal, they're nu-metal!" I can't even escape seeing some of it here at WP.
Forgive me for not understanding the purist mentality, but I'm fine with disliking many bands that fit into my favorite genres (gothic, industrial, and metal) and I don't feel the need to label everything that doesn't completely sound 100% like other bands in those genres as "pop" or "rock," because they rarely sound a thing like pure pop or rock to me. Maybe death-pop, or industrial rock, or pop-metal, but that's not the same.
And I have to wonder, what the hell is the point of debating about this stuff? What's the point in "correcting" someone about what genre YOU think a band falls into when the fact that someone "got the genre wrong" in the first place shows that it's all a matter of opinion? It's all just BS. If you can think of Deftones as metal instead of hard rock, more power to ya. If you can think of Deftones as rock and don't consider them metal, fine. The important thing is whether or not you like them.
