I know what you mean.
The only reason why i don't really learn such pieces is because of the time and effort needed to get the technique so that i can just work on interpretation. If i learn such a piece (did happen some time ago), there are two possibilities: i caricature the music through ridiculous accents and a kind of sarcasm in my interpretation, or i suddenly find out about the beauty of it.
Music you don't like can also be seen as music you don't understand (as Menuhin, a violinist, said: If you want to learn something, learn it from someone who loves it because he understands it). I think that's always good to keep in mind. But i don't have the desire to truly "understand" every music...it's ok if i like a number of composers and that's absolutely ok.
btw i never liked mozart, but i've been told that in my thirties or fourties, i will start to like him
