Sure I can bring an argument. Most of those old bands are only popular because there was hardly any music at all to even listen to. same with the Beatles (which I do like some of). When you’ve got a load of bull crap, the dried rabbit pellets sitting next to it looks pretty good by comparison. Even mediocre modern bands are much better than the “classic bands” from the 60s and 70s. You can see that with the massive increase in good music from the 80s, cause good bands actually started showing up.
