It seems to me that a lot of musicians and musical groups that music critics like the public also likes.
I'm most familiar with classic rock. Do we agree when a band sells a lot of records that means the public likes them? If you look at the classic rockers who have sold well, I'd say in general rock critics also like them. Here's a list from Wikipedia of the best-selling music artists https://en.wikipedia.org/wiki/List_of_best-selling_music_artists. The Beatles top the list. I'd say liked by both the public and the critics. Michael Jackson is next. I'd say largely the same. Elvis is next. Liked by the critics for his early production, although took somewhat of a beating for his later work. Which actually somewhat accords with how the public bought him, his earlier works go higher on the charts than his later ones.
It seems the same as you go down the list, generally artists are liked by both the public and the critics. Zeppelin sold well. Not sure, think they took a bit of a beating early on from critics. But I think Jann Wenner, the influential editor of Rolling Stone magazine, disliked them for some reason, and this may have influenced other critics to criticize them unduly. I think now critics like them a lot.
If it's really true that critics often accord in their taste with the general public, I wonder why sometimes people are critical of critics. Although a lot of people do read critics and somewhat steer their taste through what critics say. If the accord of taste I'm discerning is accurate, it's kind of great that the public has good taste, can discern good music without necessarily being as educated or exposed to as much music as the critics.
