I'm going to reply to the first post with much more gravity than it probably deserves. Either way, I will reply one "point" at a time.
A. What "sucks" is a subjective judgement, made even more flimsy by the fact that you don't really use any meaningful arguments to back it up.
B. It takes no talent... tell that to the many jazz musicians who have tried to play rock and failed miserably.
C. Not true. Much of rock derived from the blues, which is about as populist as you can get.
D. (not worth a counterargument)
E. This doesn't make sense,
F. Who cares? Personal appearance does not a good art make.
G. Also not true. Wilco, the Flaming Lips, Yo La Tengo, Sufjan Stevens, Streetlight Manifesto, Garage A Trois, and many others are making music just as good as anything from the era of classic rock.
H. "90% of all musicions do some sort of drug, illeagle or not, the most famous and best rockers have all died from drugs." Ha! Ha! Ha!
I. Drums require coordination to play. MPCs don't.
J. They haven't ripped jeans since Nirvana, dude.
K. The best music isn't always the most popular, dumbass. Sometimes it requires a modicum of intelligence to understand.
L. Not worth a reply.
M. Actually, most rock musicians are self-taught. And if they do have lessons, once again, so what? Rock is obviously not music for the rich. You don't go to see a rock band in a 3 piece suit, drinking wine.
N. Tell that to Jeff Buckley.
O. Alright, that's kind of a good point.
P. (not worth a reply)
Q. (not worth a reply)
R. Yeah, they do. Nice job.
S. "Guitars are stupid and make stupid noises" - hahahahaha.
T. Shut up.
U. Not worth a reply.
V. If someone spells "sucks" as "sux" they're probably a dumbass.
W. What kind of name is Young Jeezy?
X. Battles have also lead to many shallow artists who are virtuosic but otherwise don't have much to say. Also, art is not a pissing contest.
Y. How many female rappers can you name that aren't famous based on sex appeal? Compare that to Kim Gordon, Joan Jett, Sleater-Kinney, Ani Defranco, Karen O, Neko Case...
Z. Also, fuck you.
26 reasons not to like rock...just... arggghhh.
