Interesting thoughts there, Oopie.
I agree entirely about the time frame, it matters not when a piece of music was released. As for the visionary side of things, again, you're right. Can't say I pay too much attention to artwork these days (not like in my youth) but, as you say, even if it doesn't connect in any way, it has no bearing on the actual music in any way so why moan. It's like walking into a restaurant and buying a meal, which you find delicious, but moaning because you didn't like the plate it was served on.
