Nice one. They really don't. I think there are multiple reasons why they don't. They are the American Idol generation; the music as marketing tool generation; the it's not cool to try generation; the free music generation; selfie generation; hipster generation; internet troll generation; exaltation of the DJ generation; prefab sound plugin generation; content glut generation (glut that distracts from and lessens music's importance in their lives); etc., etc.
There were just certain rules in our generation that don't apply to millenials and Z gen kids. We had an authenticity rule. If you didn't write your own songs, play your own instruments, sing your own songs, you didn't qualify. The Monkees were shunned because they didn't play their own instruments (on the show and on the early records, later they did). Milli Vanili left the world stage over a lip syncing error! Today authenticity doesn't matter. It doesn't matter if it takes 20 people to write a Beyonce song and 35 to produce it and we never see a musician ever. Nobody cares. They just want the instant gratification. The only edge in their music is rap. Rap is the new distorted guitar/metal/grunge/etc. The problem with rap is often it's lack of authenticity too. Typically it's a conglomeration of samples to which words are rapped over. Again the musicians are not seen. It's not even called music, the whole track is called a "beat". Music is dead, dead, dead.
