But popular music itself is to a high degree very same. That's not to say that there is no original music anymore. There is a big amount. It's just people tastes that decide what becomes popular, and everybody wants to hear the same.
And yet, fashion and taste change. It's just a matter of time.
What becomes popular seems to be whatever we get brainwashed with, ie what we get advertised.
It seems to be less driven by social changes than it is driven by profit motive of those able to feed most of us 10-15 minutes of advertising within each of the several hours of media consumption most of us partake of each day.
According to him, it is not just tastes, it is the way musicians get paid:
"Streaming platforms pay artists each time a track gets listened to. And a “listen” is classified as 30 seconds or more of playback. To maximise their pay, savvy artists are releasing albums featuring a high number of short tracks."
