I used to dislike entire genres, but whenever I dipped into them, I found myself liking specific musicians.

The individual artists I tend to dislike / avoid are the ones I consider undeservedly popular. From my perspective (and I could be wrong) people listen to them because of music industry promotion (not just record labels but radio, tv, YouTube, TikTok, streaming services, music zines, etc.)--musicians like Katy Perry, Ariana Grande, Kenny G, or all of bro country. Maybe if I listened to them more, I would find something to appreciate, but I don't think so. My beef is not just that "there's no there there," but that these artists take up the listening space so that better musicians don't get heard / paid. (At one point a couple of years ago, on country radio playlists there were more songs by singers named "Luke" than by ALL women.) And my complaint extends this way: listeners will often gravitate to what's new, regardless of quality, and ignore good stuff from the past--and by "past" I don't mean just the Classic Rock era, but music even older than that--e.g. the latest Eric Clapton nonsense gets played / reviewed but not Mississippi John Hurt.
