OK, when you use the phrase, "stand the test of time," you are now required to invoke the Grateful Dead as your prime example. I realize now that those long afternoons having a great time while these guys noodled on their guitars in their tye-dyed underwear had NOTHING to do with them. It was like elevator music for the experience. I guess that's what made them so popular. But I dare you to listen to their albums now with a straight face. Go ahead. I'm waiting. It's just hoopty, isn't it?
Addendum: I will say that I still love American Beauty but I cannot think of another of their albums I'd still listen to without cringing at some point.
