Pretty much same for me. Listened very casually/cursorily/briefly in my late teens, tried a few times again in my 20s and 30s, and found it kind of boring and unexceptional.

Then in my early 40s I dug in a bit and really started actually listening and exploring. And oh man what a wide universe of musical discovery burst forth for me after that. And I couldn’t believe that I didn’t put in a little effort earlier..
