Why do we stop listening to new music as we get older?

My nephew and I share and swap new music all the time. Conversely, I rarely add new recordings of "old" music to my library.

Yeah, there have been several studies that show that the vast majority of people stop discovering new music around the age of 30. Some say 33.

The most likely reason, is that from about one's mid teens up through their mid to late 20's, people are experiencing some of the best times of their lives. And the music they and their peer group listen to, becomes the "soundtrack of the best times of their lives". New loves, great wild parties with friends, going away to school, newly discovered independence, etc, etc, all with the music of their time playing while it is all going on.

Their experiences become inseparable from the music.

Music that comes after that time period of their lives, even if it is qualitatively no worse (or no better), does not have the same kind of connection. It is 'only music' now, it is not their soundtrack.

I actually have hardly any nostalgic feelings connected to music at all. I am never trying to relive my youth through music.  For me, music lives or dies based on its own musical merits. Either it has the attributes I love in music, or it doesn't.

I'm way too comfortable with my old blues music and don't do much exploring of new music, only occasionally.New arrangements of old music is interesting though.

 I can’t agree with this at all!

I’m older and I still like looking for and listening to new and new to me music. Heck, that’s the main reason I bought a streamer.

I am constantly finding new music. I occasionally play an album from my collection. 
 

The amount of new music has escalated exponentially since my streaming / digital side sounds as good as my vinyl.
