I think you’re confusing mastery with marketability. “Other people want to hear it” is at best adjacent to someone’s skill at composing or playing music.
There’s plenty of mediocre musicians who became world-famous, and plenty of great musicians who nobody’s heard about. Skill and success are pretty weakly correlated.

This is a fun and complicated topic. Yes, sometimes things outside of the music influence our perceptions of the music. If the Red Hot Chili Peppers were a bunch of bald fat dudes maybe they would have had less fans; if Kurt Cobain hadn't killed himself he would still be a legend but perhaps in the calbire of Eddie Vedder and not what he became. But the following underlying principal I believe to be true : it's impossible to survive the test of time in music without producing "good" music. Example of music that survived the test of time : The Beatles, Queen, Pink Floyd and I'd argue Nirvana, Pearl Jam etc. How do I define "survive the test of time" is another discussion I'd rather not get into lol.
