If I had to guess, the unwillingness to find new music is probably strongly correlated with increased isolation as one ages (from meeting tons of new people as a kid because you didn't know better, to entrenching deeper into your cliques throughout middle and high school, to meeting tons of new people again in college, to re-entrenching into your clique as a working adult with no time to make friends, to re-entrenching into your family as kids and the commute from your suburban, car-centric neighborhood to your urban, car-centric business district and back consume your entire life). There's probably a factor of listening to music from the "good times" as an escape from the monotony and dregs of daily life consume most of people's days too. I remember TV, music and events from the 90s and 00s, but nostalgia does nothing for me. As for me, the "good times" of high school were terrible for me, I lived in NYC basically on my own during college, and I'm 35 with no kids, so I haven't stopped discovering new music (or myself)! In fact, between Last.fm (still up and running!), Bandcamp, Apple Music, Spotfy, and automatically-generated New Music Mixes, the amount of new music that's out there is almost overwhelming!
