Couple o' random points...
On Bieber hatred it seems a lot like a "doth protest too much" thing many times. I mean, its everywhere...it is the popular thing to "hate" Justin Bieber, statements to which effect are almost ubiquitous on Youtube, but seriously, from my perspective he's a kid cashing in on vapid popular music and he apparently does it well and is making a nice pile of cash out of the deal. I salute him, even if I can't hum a single bar or name any of his tunes. I doubt if even he really believes his is terribly exceptional music...he's just providing a product that is apparently very well received by the younger female set and is handsomely remunerated for it. Good luck to 'im!
Also remember that when you think your music is GOOD music and lesser pop music is trash, there's always someone snobbier than you who thinks your pop trash is dull, uninspiring bilge based more on image or marketing than actual musical genius.
I did have another point, but it has eluded me in my mockery of Bieber-bashing, which at least in the childish comments of Youtube appear to be a lame one-upsmanship where people brag about how much they think Bieber sucks. I probably would detest his music too, but then the same goes for scads of crappy bands that think highly of themselves, that I have never forced myself to listen to.
