You just gotta know where to look. Music is an industry, so the people who view songs as products will push their favored products in front of as many of their target demographic as possible. They want those tween-to-twenties locked down. They decide what's cool, so if they like your products then you're cool. So if you're 40 and only listen to top 40 pop stations, you're probably in for a bad time since none of that shit is really trying to court you in the first place. I'm in my mid-late 30s and I'm still discovering bands and current releases that I'm into. Just gotta look a little harder.

I think that as we get older and consume more media, we experience a sort of fatigue of simple and easy structures, so we desire something more complex. But we grandfather in the stuff that we imprinted on in those formative years, and that's why that younger demographic is targeted; they'll keep coming back to their comfort media for their whole life.

Pop music is (usually) the middle ground between nursery rhymes and something like djent or cool jazz or math rock or whatever other more nuanced genre you're into. "Products" in those genres just aren't gonna sell like boy bands do. Some pop music is actually good and complex, but it's just not my thing and mostly never has been. I'm not trying to insult people who like Bad Bunny or Kendrick or whatever, but yeah Black Eyed Peas and Kid Rock fucking suck. Don't @ me.
