The funny thing about the Snob is apparently that classification is responsible for roughly 97.6% of the music reviews written online.
Remember when we had heavy metal? Just heavy metal? Oh, sure, by the 80s we were starting to get a wide enough spectrum of metal that the occasional modifier was needed-thrash metal, speed metal, death metal, black metal-but you could call Motley Crue and Celtic Frost heavy metal bands and most people would get the point.
These days? Oh boy, these days. These days a band isn't a band unless it has at least three or four different modifiers to the base genre. "PostSludgeMetalgazeCore." (You laugh. Just wait, someone, probably a writer for Terrorizer Magazine, will coin it.) Sometimes you can have two bands separated by the slightest of differences with two utterly different sub-sub-sub-genre names.
It's gotten insane. I'd rather live in the world where Slipknot and Korn are called heavy metal than live in the world where a band with seven words in its name is called "extreme melodic crust gazecore."
Mind you, I grew up when any remotely progressive metal band was described as "they sound like Rush," so YMMV.
