I guess if by "pop music" you mean everything that gets played on the radio, gets aggressively promoted by the recording industry, and has the widest audience I'd argue that many people should care. It's great that there are awesome musicians who are putting out amazing music in their basements or at local shows but if 99.99% of the population will never hear it does it matter that what they will hear is watered down crap? I'd argue that it does. Even your own examples show only a few thousand views. Compare that to what a currently popular song (https://www.youtube.com/watch?v=zlJDTxahav0) has seen in views over just one week. The song isn't even bad, but I can see how it could be described as "simple".
There's no shortage of worthy and soulful music. And it's more accessible than ever.
Maybe there's just more music in general, and that is easily mistaken as a consensus rather than just all-around growth.
It sounds like you didn't read my comment in full.
If you are looking at the kind of music that makes it onto Top 40 radio stations, then this is undoubtedly true. But that's not what is meant when you say
> For the past 30 years music has definitely become more "bland"
When you suggest that, you appear naive and ignorant. Because it means you don't know about Tyshawn Sorey [0], Mary Halvorson [1], Anthony Braxton [2], John Zorn [3], etc.
Pop music, a tiny sliver of all the important music being composed and performed today, has gotten progressively shittier. Fine, I'll grant you that. But who cares? That's not what we're talking about when examining the vast complexities being propagated and explored by today's musical masters. We are in a golden age of harmonic and compositional innovation.
