There's no reason to complicate your thinking about tastes and aesthetics. There is art that you like, there id art the you don't like. Then there are criteria by which you judge the quality of the things you like/dislike.

For instance, it becomes hairy once you get down to make any sort of meaningful comparison between the quality of musicians you like, even if the criteria are pretty meaningful. Is Chopin better than Katy Perry because his works are harmonically richer? Bach because of superior use of counterpoint? Maybe Ivan Wyshnegradsky for his use of non-standard tuning systems?

Something is good if you are able to appreciate and enjoy it. Trying to justify why you like/dislike something is not going to be very fruitful in thr grand scheme of things, unless you just want to find similar things that you'd enjoy.
