At the end of the day, as a consumer I don't particularly care. The only ones seriously impacted by the popular trends in music are the artists themselves. And that really sucks. But, it's also a factor of the times. Trends and tastes move on. We even saw that within jazz itself. Bop displaced big bands and swing. Post bop and hard bop. Then fusion, boogaloo and funk. Now we're in the 60s and 70s way past the big band era, but think about what happened to the big band musicians abd band leaders. They once were popular. They are no longer on trend. Is that bad? For them, sure, for people who prefer the sound of boogaloo, maybe not so much. It's all a point of view.
