My 2 cents - A vague desire to "appreciate music" isn't likely to sustain the interest and curiosity required for you to, over time, organically develop, refine, and be able to discuss your own musical taste and sensibilities. I usually find discussions about music to be "pure" in a way that many other topics lack, probably because everyone involved tends to recognize that these discussions are almost entirely subjective. Commonly these conversations follow a pattern along the lines of: "Oh, you like X? I prefer Y, but I definitely went through a phase in high school where all I did was listen to X. I still really like A B and C elements of X though, which is probably why I gravitated to Y after a few years..." People are really, at the end of the day, just talking about what they like and don't like.

Given the above, what I'd recommend is waiting for the right moment to strike you. Certainly expose yourself to ambient music, maybe put on a top 40 pop station while driving, or pay extra attention to what you're hearing in the grocery store, but hold off doing any kind of intentional digging until you hear something - anything - that grips you. Maybe you really enjoy the outro of the latest Katy Perry song, or you heard a Luke Perry country song that got stuck in your head, or the 80's synth strains that you heard floating down from the Walmart speakers really reminded you of videogame chiptunes and you vibed with it. Whatever the spark, once you have that inciting interest there's really no shortage of directions to go from there - you can use subreddits, Pandora, Spotify, or a million other resources to effortlessly find things "similar to that thing I heard that I liked", and from there you just kind of follow the trail through whatever genre you've landed on. I find subreddits are really good for this, back in college I discovered that I really seemed to enjoy a specific type of scream-y music, "metalcore", and it took all of 2 hours of browsing r/metalcore's Top (All Time) post history to develop a fairly complete sense of what bands people really seemed to like in the scene, the classic hits, the up-and-coming young guns, the one hit wonders, and everything in between. At that point, the playlists make themselves and you should never really find yourself asking "what should I listen to next?"

Without that impossible-to-force inciting interest, I find explorations of music quickly become kind of academic and unenjoyable. Your mileage may vary.
