Some very interesting perspectives here. For myself, while I do wish I could listen to more "new" or at least unfamiliar music, it's really a matter of time. I'm older but still work full time in my own business & enjoy listening & relaxing to music that moves me but often I don't have the time and / or energy to seek out new stuff.
Additionally, I only recently got into streaming w/ a really nice set up w/ a good tube amp & good speakers set up well so I'm hearing things & enjoying music I thought I knew well even more than ever before. Hopefully when I retire this will change & I can explore lots of other great music know is out there.
