Age 13-29, I mostly had oodles of free time to listen, explore music and a network of friends sharing their discoveries. Age 30-40, I got really busy and had more people involved in my professional and private life so it became harder to fit in music exploration (something I really enjoy). And less friends sharing their music.

I think streaming has a lot to do with this as my parents had a monthly record club they organized. A bunch of friends with their kids got together at someones home, made dinner, drank and listened to new music in the background.
