man, i was gonna ignore this topic, but you have not made a very compelling argument at all here i don't think.
marketers and industries have finally become successful in selling rebellion. you see somebody like hannah montanna going for the rock cliche which is so generalized today that anyone with an electric guitar can look the part.
why are you making this claim like it is something new? all of this has been true for probably longer than you or most of us have been alive. MARKETING REBELLION and the rockstar cliche have been around for decades pal
then we got this
ok, there have always been those artists that have borrowed an older style. but there have been more and more bands that don't just take a page, but a whole chapter from hair metal, jangle pop, or glam rock these days. 80's have especially made a comeback. with bands like wolfmother, white stripes, the hives, hinder, buckcherry, franz ferdinand, the minus 5, the strokes, etc. there's no need to make anything new if people are eating it. this contributes to rock becoming a novelty (#3)
tbh i'll admit that probably at no point in time in the history of modern music were people coopting old styles than this past decade with _____-rock revival and whatever else. buuuuut you are focusing on the most bland commercial music and generalizing about an entire genre. to begin with you've got the issue of the concept of ROCK being incredibly nebulous at best and meaningless at worst. what do you mean by rock? what qualifies as rock, what doesn't, and why?
but alright movin beyond that, yeah, rock aint dead if you bother to think this question through beyond hannah montana////jonas bros???? FUCK THIS SHIT. there are tons of interesting rock bands around now, and a fair amount who are trying new things instead of just taking a page out of something someone did 20-30 years ago. so ya people still do new/intriguing things in rock and there are still legitimate rock bands out there (see: wire). anyone who says rock is dead is dumb or not looking very hard, because the SPIRIT OF ROCK or w/e lives on and not by a small amount if you just pay attention to anything that isn't on mtv or the radio. whoa lets base our conclusions of an entire huge genre of music on the single most commercially-driven facet of it.
