I don’t see it that way. To me, it seems that there is a lot more great music available, and it takes much less effort to find it. Mass-market music is lowest-common-denominator crap, but that became the case somewhere in the 90s and hasn’t changed since.

The sweet spot is to find artists who are popular on streaming services, but not nearly as popular as the heavily-marketed acts that fill stadiums. Then branch out from there. Maybe check out community playlists that don’t contain big name acts and add anything that resonates to your own lists to get started?
