Rock isn't dead. It's just being outplayed by much of the crap that millenials and rappers come up with on their computers and call it music. "Popularity" is nothing more than crowd/herd mentality. Sadly the crowd at the moment is mentally ill. I have a step-son who in fact is a music producer for a large ad agency (and has actually won a couple Grammys). He puts on music and after awhile I have to ask him to put on something different before I put a bullet in my head. And trust me, I like (almost) all kinds of music. But some of the stuff today just drones on and on and on and on and on and on... you get the picture.
