"Rock is dead'. Depends on what you mean. The idea of a rockstar being a drug filled , total sex addict, loud guy. Yeah that seems pretty dead. Does most rock play the blues scale, not so much anymore. But foo fighters will still pack a show, and so will green day show. Rock is changing, and the amount of people that listen to it seems to be lowering to a good amount. I wouldn't say rock is dying, but not as relevant for most bands. Probably due to the fact us lovers of rock tend to be extremely close minded about trying new things. That "things should be like the 70s" mindset really keeps alot of us from making new music
Personally, alot of rock on the radio tends to bore me. Just my opinion, i prefer more metal and hardcore. And those styles are not the most popular of course.
I end up just listening to the dance tracks on the radio. Lol i don't care. Those beats will drive people insane on the dance floor. And isn't that what rocks about too? Going wild.
