Getting into the music

I don't feel like this all the time, but the older I get, the more and more I feel like what you just said. 

yes, I understand and can relate. On the plus side, I find myself to enjoy listening in ways I haven't in the past. It's a deeper, richer experience with better sound. 

It sounds like you're overdue to get out and enjoy some live music. Or, make some music of your own,.

Been there, done that. I solved this problem somewhat by intentionally dumbing down my system. Apart from my speakers, there is stuff out there that is much better than what I have now but I ignore that, don't think about it. I try to make my few appearances here to be helpful to others, don't read reviews or subscribe to magazines, and don't talk much about what I have or have done unless it is serves to help someone else. I guess (and hope) I've been able to reorient myself and focus on the music. Hang in there, there is hope. :-)

One thing that has helped me actually increase my music appreciation is streaming in random play mode. Roon and others offer random play functions.

For me it’s like when I was a kid and hearing things on the radio is how I got into listening to music.

Except now it’s even better. You can pick the music that goes into your music library and let it play randomly. You hear only things you want to hear but do not have to decide what listen to next. Surprises abound and that is important. Removing the burden of having to decide what to listen to next helps me just relax and enjoy the show.

I started doing this about 15 years ago when I too found myself lacking interest and it has helped keep me in a very good place ever since.

Hoping this might help .
