I know this topic has been done to death here, but I heard this podcast on BBC and I thought it was worth a listen: https://www.bbc.co.uk/programmes/w3csytgj Not revelationary by any means, but I enjoyed it. I especially liked the second interviewee, talking about the economic side of making rock music vs. for example hiphop. EDIT: Just to make clear, it was not my intention to lament the "death of rock music" or to pit rock music against hiphop music. My view is that there is a LOT of great music being made today in many, many various genres, including rock. I don't think rock music will die, it will exist in one form or another, but it will probably not be the "dominant form" of popular music anymore, as it used to be. And if it does "die" (whatever that means), I'm sure there will be other interesting things to listen to. I'm not even such a big rock music fan myself. I just thought the podcast might be an interesting listen.
