Just thinking about this. There seem to be certain types of music that just about everyone likes. Classical is one, no surprise since there’s around 800 years worth of it, so everyone will like something. The Beatles. Billy Joel. Some form of Motown.
Then there’s music forms like country, rap, and opera that are much more culturally tied. In other words, you’re either raised in a culture that likes them, or there is a very strong chance that you don’t. Of course there’s some softness around the edges since musical genres are just commonly agreed upon false hunches at bottom, but for the most part, this obtains. It’s just interesting.
