I almost want to apologise for introducing Nickleback and Nelly Furtado (and Burial) to the argument, as I was really just making what I thought was a baldly sarcastic remark, a bit of a canard, with my invocation of them and the bogey-man Rockist-"Korporatist".
I find a rather irreconcilable hypocrisy in most Anti-rockism/Antirock-ism/Popism/Futurism, in that these isms provide no mechanism for dealing with the possibility of rock-as-pop, rock as a music (or a trope of "authenticity") as "artificial" as the ostensibly more knowing and hence more honest pop music posited as inherently (morally-musically) superior to rock. That is to say, if rock music becomes popular, there is some sort of false consciousness at work, some sort of reactionary anti-intellectualism-cum-authenticism that is impossible in any other form of music (despite established traditions of "true" jazz and "the real-hip-hop", etc.).
I personally despise Nickleback--their image, their packaging, their marketing, their music. And I happen to enjoy the Timbalanded Furtado, and local darlings Burial (though not with the fervour of most). But I recognise that my preferences are simply aesthetic--if analysed, I'd say at least the former two are equally "korporate kapital," equally likely to be designed-by-committee top-down artefacts of no particular "people" however "popular" each may be (and surely, though I guess I don't know, Nelly's "Promiscuous Girl" is getting more airplay in the States than any Nickleback tune, despite the dastardly Liberal Zionist Media. . . er, I mean, the Stoneagist Hippie Rockist Media [/sarcasm]).
It's telling that at least a few people here seemed unable to detect my offensively brattish parodying of the confusing, dominant line of thinking re: rock vs. the "peoples' music" and took me at some sort of face value. I guess I have to say it more pointedly: none of it is the peoples' music if it's marketed, if anyone bigger than a room of ten people hear it--and thank goodness. I don't care rock pop grime hyphy proto-neo-elecctro-klezmer--it's all part of "kapital" even if it's for free, and so ultimately it's a fairly useless criterion--the (accidental?) authentic-fetishising of honestly inauthentic pop music is stupid whether by the pure-pop camp or the dinosaur-rock camp (neither of which, thank god, seems to much exist outside of messageboards full of nerds like us with too much time and obsession on our hands).
Either "the people" honestly love their Nickleback and their Timberlake; or they're all programed sheep of the kapitalist-hippie News Corp-NME bourgeoisie--but they're in it together. Arguing over which one is selling out the right way grows tedious. For whomever asked if my preferences could really come down to the sounds alone, barring all the cultural/subcultural trappings---as far as I can tell (I could be suffering false consciousness, I guess I wouldn't know) indeed it does come down to what goes into my ears. I can enjoy all the rest in its own right, I can geek out of connections and reactions as much as anyone here--but at this point in my listening addiction, all that is truly tertiary in comparison to the visceral and intellectual effects of the sounds themselves. Maybe that makes me a dilettante, to simply "likes what I likes," but I'll take it over the endless side-choosing fanaticism engendered by the tropes and politics and economics surrounding the sounds.
As for the benefits of fanaticism--I think some people are using that word as I would use "passion," except that passion is never antithetical to eclecticism, and for myself it actually begat eclecticism. My passion for sound was too big for any one sound-box, so it inevitably spilled over and took me to new places. I feel like any sound-strain that becomes self-consciously "pure" is going to die out--genetic diversity, as it were, is as necessary in music as it is in nature for anything to thrive. So passionate eclecticism, not dogmatic fanaticism, is what allows music to change, grow, adapt, survive and thrive. Conflating fanaticism with progress is to me a surprisingly old-school view of history, wherein only the Biggest Men with the Biggest Cocks who win the Biggest Wars matter. Eclecticism is for me more in keeping with the more progressive view of cultural history, which recognises daily, quieter creativity as equally important as Big Moments of Destruction.
I'm saying none of this well, as it's not something I've particularly spent time sussing out in so many words for myself till now. But lets at least put our dear friend-enemies Nickleback and Nelly to bed for the discussion, and get back to the meat of the matter.
