>>19995344fpbp, popular music has always been a marketing enterprise. Rock had it's time in the spotlight and the financial and media backing that that entails and now it's over.
Rock itself is not dead but eh mass media spam of it is. No more Nickelbacks, Creeds, and Breaking Benjamins on the radio, now you have to dig through streaming services to find it because market research shows that people who spend money don't tend to enjoy rock.
