I think we all go through what the OP described. In my case I retired 2 weeks ago and my first task was to straighten out my listening room(s), which meant organizing a lot of physical media. In the course of doing so I encounter many long unplayed recordings and I’ve been listening uncritically from an audio standpoint and having a great time. I recommend the OP go wading into his vast collection and just play whatever grabs his fancy
Getting into the music
I’ve found, to my dismay, that it’s very difficult for me to listen to music for the music itself these days. Since I got into this audiophile game many years ago, little by little my musical appreciation has eroded to the point that I find it very hard to comprehend the music itself if it doesn’t sound good. Too often I’m listening for sonic delights rather than the message the composer is trying to convey. I find myself going from composition to composition looking for audio niceties. When something sounds good I can then begin to get into what the composer is saying.
As a former musician, this would have been unthinkable years ago. Music was everything to me.
