The answer is in the question. It is an antinomy.
We can take many examples if this dialectic is not clear. (Any resemblance to a situation etc.)
1) I don't like Picasso (all periods), I don't care about his contribution to scribbling on canvas. So
2) If the Beatles hadn't existed, I would have liked Jerry Lee, Elvis, Johnny Cash or Vince Taylor more.
But they existed and the Stones said tons of times that they wanted to do like them, write songs that are slices of life and not become or remain in this specific case a dance band that covers a few blues standards.
If I meet a girl I don't like I'm not going to say that she's pretty but not my style (borderline case because age will also play its role).
First point. For Picasso, there are a few pieces that blow me out of the water, but I find the majority of his work doesn’t resonate at all. That doesn’t mean I can’t recognize his contributions and place in history. Also he didn’t work in a vacuum and invent cubism on his own. I find Brechts work to be as historically important and more of his works to be personally relevant.
Second. There are many people out there who if I was asked, I would describe as attractive or pretty or beautiful because I know that by average societal standards they are. It is a very small subset of those people, usually following a fairly similar pattern, that I actually feel desire for.
Both of these hold for music. No musician comes up with a style or genre out of thin air. There are always many multiple musicians working at variations of the same thing. Some of those things will click with more people than others. Part of this is totally personal. Much of it is social pressure and exposure. History is largely a navigation of those two elements and historical importance is a measurement of how many people clicked with it or were indoctrinated into liking it.
Influence, to me is more intriguing. Probably the single most relevant influential band for grunge was Green River. Outside of the NW scene, not that many people have heard of them. Very few people like them or enjoy their music, relatively speaking, but without them it isn’t clear that grunge (and by extension much of 90s US music) would have happened. I also don’t choose to listen to their music. It’s fine and well constructed (like the Beatles) and I recognize it is “pretty” by societal standards, but I don’t desire it.
Also, FYI, I am reading that you are arguing in ways that either diminish those you argue with “you don’t actually think what you said you think” or are kinda totalitarian: “if society says something is important, you personally have to like it”.
