Nah, that would be fine. Pop culture isn’t cool. Pop culture is (mostly) boring shit for the masses, because it is bland enough, that a majority of people don’t have an issue with it. You are fine if you only hear about it from your grown up magazine.
Dito, but I downvoted. The balance is restored.
There never was and there never will be a sustainable dictatorship of the proletariat. The only ones that tried that really hard where the Khmer Rouge and those murderous fucks are an excellent example how to ruin a country as fast as possible.
Hey, I really don’t want to talk you down or be destructive or anything. My point is on the contrary:
You are not uncool, lame or whatever, if you don’t know contemporary pop culture. There are some fine songs, everybody likes. They become classics, as you say. Most pop shit is just a short-lived fad, nobody will remember in a few months. If you like that kind of music, it is also absolutely fine.
