The problem is that most millennials are overwhelmed/overwhelmingly favor yukky music and the good music is shoved aside. The live performances of musicians are where the money is rather than in studio recordings cheaply available on the internet.
schubert, after I met my wife, I was introduced to more modern rock from the 70s and 80s and enjoy much of it now (not so much heavy metal). From my 40s, I was introduced to modern jazz. So, my music tastes have evolved over time. It began with opera, classical, pre-1960s pop and ethnic music from childhood. I have a large collection of jazz now which makes listening frustrating as I have 42,000 LPs/78s/CDs. One day it’s one format, another day another but jumping from one music genre to another. I can’t hear it all.
