Honestly, I used to focus much more on how objectively interesting music was. I got into Frank Zappa and started down the very deep rabbit hole of his discography, and eventually realized that I really loved some of it and the rest was just... not enjoyable.
Speaking as someone who has been writing music for quite a long time, writing something that is objectively interesting (by being complex or unusual) is much, much easier than writing something that is just plain entertaining.
I think there's always something to be said for pushing boundaries, and I love experiencing any art or entertainment that makes me think "oh shit, I didn't know you could do that." But even then, that doesn't make it good or enjoyable, just interesting or thought-provoking. They're not mutually exclusive, but they also aren't necessarily correlated either.
