I see your point. It is very good and valid. Nevertheless, popular music is generational and passes along with the generations. So what that somebody’s grandchildren are listening to the Beatles (as reported on this forum recently and repeatedly in response to posts like mine.) Dollars to donuts that their grandchildren won’t. My own daughter, whom I raised on Vince Gill and Patty Loveless, later a Green Day fan, once fell for the long dead Gram Parsons. Who? I never really appreciated him myself, before or after.
In addition, something that I only recently discovered (dumb! dumb!), people judge much of popular music, especially live performances, by their experiences while listening to it. You can see it by reading comments on Youtube under godawful live performances by the Rolling Stones (or anyone, I suppose). I was there (meaning, I paid the exorbitant price for the ticket), I had fun with my girlfriend there, therefore it was good.
On Fakebook, while I post links to videos and free downloads by Filligar and Nicki Bluhm and the Gramblers, among others, my “friends”, who grew up with the Swinging Blue Jeans, not only fail to click Like, but respond by posting links to Gerry and the Pacemakers. Stuck in their youth. And I bet they say that Elvis will be forever, and Beatles too.
