Anyone who was involved in (or otherwise has a perspective on) the popular music of the 20th century can hardly escape the impression that things have been dumbed down to a strained degree these days. Traditional sensibilities of great songwriting, both musically and lyrically, seem to have gone down the drain, replaced by monotony, crass self-assertion, braggadocio and even aggression. Basic reflectional nuances of expression, such as humor, irony, wistfulness, melancholy, and reminiscence itself, appear largely dysfunctional in this millennium. The now is all.
What used to be "rock" proliferated into a myriad of narrow sub-genres of some "metal" variety, most of which center on personal instrumental virtuosity, quasi-heroic egoist mythologies based on half-baked philosophical or occultist notions, and a general angsty defaitism towards humanity. MTV was sold and promptly turned into a channel plugging misogynous gangsta rap, spurious "glamour" R&B and unfathomable award galas. Crossover country is the genre that retains some elements of what used to make for good pop music, like the combination of savvy chord progressions and meaningful lyrics.
On the other foot, sound technology is richer and more diverse than ever. It's just the content that is mostly missing. For the kind of substance I'm talking about I find myself going back to '30s/'40s calypso, old delta blues, Hoagy Carmichael, Cole Porter, things like that. But I do like e.g. Snarky Puppy for what they do instrumentally, and am listening out.
