Moments of greatness, but how can you say they're good?

Irrelevant Rant----------------------------------------
In a record store like Kim's, how are these "genres" relevant at all when bands seem to be classified simply by a shut-in retard? For example, today I found Roky Erikson, Swans and Windsor For The Derby in "The Establishment". Windsor For The Derby right next to Neil Young. Make sense? Established? Then I found Boredoms in "Avant Rock" and Flux Informational Sciences in "Indie/New School" just below Diamanda Galas. Most of the Young God Records catalog is filed under "The Establishment" (yet they are all avant rock, for sure) but the really interesting thing is that the Young God Records Compilation sampler is found under "Experimental". Interesting! Jarboe from Swans on Young God is somehow Avant Rock, however, despite the fact that she is as old as the Swans and less avant garde than Flux Informational Sciences, for instance. That puts the Swans owned Young God Records into all of the available categories except Reggae, Techno and Psyche, for a label that essentially produces the same kinds of artists: evil, droning, avant rock.

ANYWAY, all this sifting through this-or-that which needs to be classified specially under something other than "rock" made me start thinking about all these supposed geniuses. Half of the cds I looked through today were utter shit. I knew most everything I came across and understood that somewhere someone had some album by some of these bands that thought this album in particular "solidified [band's] place in rock history as blah, blah, blah" when most any album has filler and most artist's catalog is speckled with failure.

Who are some bands/performers/artists/avant-indie-experimental-new school/rockers -- hell, even producers-- who you feel are just plain given too much credit? I don't want to give my opinion, actually, but I'm eager to hear yours.
