So true. A lot of my "OMG I LOVE DUBSTEP" friends would classify me as a "dubstep hater," because of how much of their favorite music I can tear to shreds. I don't hate the genre of dubstep, I just hate the fact that so many garbage, bedroom producers can put their half-baked crap out there and get so many fawning fans.
To me, dubstep is an exercise in production values. I even dig a lot of Skrillex, because he did what he does FIRST, and he did it with polish. Noisia are one of my favorite bands, and I've been able to see (via studio tapes and interviews, etc.) how much work they put into their production techniques (plus they started out as dark DnB--another "exercise in production" genre--first, which they absolutely rule at).
The best dubstep music, of course, is when you combine flawless production values--slick synth patches, clean mix--with a well-thought-out melody line and chord progression. If the mix isn't clean, if the drums are generic, if the synth patches have been used in every other "dubstep" song out there, then the song is garbage to my ears.
Granted, I've always admitted that I am first a producer and second a musician. My standards tend to be insanely high, and the average listener might not care. I just wish the average listener could learn to be a bit more discerning with what they consume and what they praise.
