In a generation, there’ll be similarly myopic people saying the same thing about, say, Pearl Jam or Justin Timberlake or someone. And from a subjective point of view, they’ll be equally right.
They used to say similar things about Elvis Presley. Then those to whom he meant a lot died off and his timeless significance mysteriously faded away. Those who paid a fortune for rare Elvis 7”s can’t sell them.
Elvis Presley is timeless too. Same with Pearl Jam. Just because it's old music doesn't make it irrelevant, just because it's irrelevant to you doesn't mean it's irrelevant to everyone else.
