"culture" vs. "pop" culture vs value

What matters vs. what do I like vs old school entertainment that supposedly hold more weight than more modern forms. I can't lie that I try to absorb all this stuff because I'm not interesting but the things I am exposed to make me seem interesting . . . isn't that true for everybody? Isn't that from "High Fidelity"?
A friend was teasing me that I had no culture but I argued that I'd been to symphonies, I'd been to The Nutcracker, I'd been exposed to famous works of art, she argued that I would still be happier at a rock concert. I didn't respond or retort, why waste my breath with words that can't back up actions, after all I'm just a man not the son of the sun king.
I'm not exactly sure if there should be a difference between any of these things because they all made money, they all convey some sort of information, they all make people happy or feel something and maybe a grand opera tells the same story as an Aerosmith song. So there's Andy Worhal who was like some flake who said simple cocktail observations and did some art because there wasn't anything easier to do. While doing this he invented something for people with nothing substantial but not before getting art critics to go for his schtick. I actually don't know if any of that is correct but it sounds about right.
Is classic art important beyond asthetics? Personally I feel that if it can tell a good story with something interesting to say. The Greek plays or poems are a good example of this as is the next versions of those in the form of Shakespear . . . now we have Stephen king.

Have I mentioned that I have this odd hunger for sugar cereal lately? I just want to chow down on some sugar pops. I don't know why but there it is. Steak and eggs also sounds really fork licking good too!

I guess none of this matters because it can all come down to generational themes and technology. We are humans and have a lot of free time which most of us choose not to do anything important with so we need to use up that time with entertainment and leisure activities . . . so even sport gets thrown into the mix here. Athletics are important because it can represent what we are physically capable of even if we need performance enhancers. I don't know what the Ancient Greeks and Egyptians used to make themselves better in competition but certainly there was a modern idea of cheating going on.
You know classic books have more references to their times than you might expect, making them essentially pop items before the term was what it was. I like a book that can capture a time without being obsessed with it or being so much a product of it's time it doesn't transcend it.
