I'm late to reply but for the record I think you're way wrong about music. You (and I) are just old. I'm a musician and I do think there is a sense in which the most popular songs are "worse" - they contain fewer, simpler musical ideas. But there are plenty of good song writers doing interesting stuff. I'm not totally on the ball as I do prefer music from the past. But I would point to Billy Eilish as a particularly young example, there's also Jacob Collier for instance. Both very unusual, very popular.
