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

Well for me "new" music sucks, It's all Auto tune.  Mostly computers playing the instruments.  Really last newer band for me was Audioslave.  I mostly stick to 60's 70's 80's 90's

Oh you can stick some late 50's in there to,  I'm 52 by the way.

Roon's ability to play or suggest new music to me has enhanced my music enjoyment far more than any gear upgrades that I have made.

I agree with you.

To the OP, the answer is - if you do stop listening to new music, you are only cheating yourself.  Listening to new music does not mean you have to like the old stuff any less.  Abundance, not scaricity.  You should follow your own advice,

With the maturing of streaming as a music delivery platform, and the ease of being able to surf new artists and music, it might be time to break my old listening habits and find some newer artists.

One possible anaysis might go:

With the net and digital, production and distribution costs of publishing music are almost nil.  So millions (and millions) of recordings of new music are now published annually as against certainly no more than 10,000 a year 50 years ago.

Not all music is of high quality or worth publishing at all.  Most of it would not be published if publication cost what it used to.  We can't all be great composers and performers.

The fallacious conclusion is that means more music to choose from.  But the correct analysis is that you are more than 100 times less likely to find you like a piece of music you try.  Therefore it can be said that trying new music is an unrewarding experience, at least in terms of time spent.

Someone said it well already, we form the soundtrack of our lives when we are young, and no matter how much new music we may find, we have in our heads music that is linked to memories of previous times and places that is custom to only our personal memories. Being older now I understand when my parents would say the current music is garbage. They never listened to rock n roll, they never searched out new music. They were mentally locked in the past musically. While I will not let that happen, I still think there is a lot of garbage music out there that is simply not musical in any way. I think this is always true.
