I think this is an attitude that changes with age, experience, musical knowledge. It's the equivalent of a teenager thinking Blink 182 were the bee's knees up until they really
hear, not just passively listen, but really 'get' Pink Floyd or Led Zep or some other classic rock giant for the first time. Like a musical awakening. It doesn't mean that old always = good...only that you develop a completely new appreciation for how that old, classic stuff is timeless, how much influence it had and how much depth there is to what makes it so landmark.
