A discussion starts. It has promise; content, even.
For example: "What bands made better albums at a time later in their careers?"
It reaches an apex and people find clear examples in the old school bands.
For example: Carcass, Bolt Thrower, Deceased and Megadeth.
And then in comes a stream of people, shambling and hiding behind their bullet belts and vest jackets, etc. who mention bands no one except a niche-clique cares about.
For example: "Oh, definitely CHRIST INSERTION and NECROBOMBAST. Maybe DOG OF THE APOCALYPSE. Yeah, that's the ticket."
It seems to me that's what crushes metal in general. Everyone must participate, and for that reason, they invent importance to music that is irrelevant drivel in the big picture.
Outside of the niche-clique, no one cares about your local bands, your novelties, and flavor of the week. This stuff is a self-referential group selling stuff to themselves. It reminds me of how the Western nations are now structured around a "consumer" population that seems oblivious to the fact that, outside of our fat-lazy prole-ocracies, Kesha and Jodi Piccoult are worthless drivel.
