. . . And why?

For a long time I never cared for Chopin's fourth Ballade, but now I love it (since a couple of years now I guess) and think it is wonderful. Not only did I not like it, but I didn't think it was a great piece. But I don't know how I came to love it. I remember telling my teacher I didn't like it and she said she didn't like it either.
Sometimes when we hear a piece for the first time played not very well or to our liking, which we then discover was the case later, can be the reason why a piece strikes our musical palate 'blah.' I believe one such case for me was with Chopin's first Ballade. The first time I heard it played by Peter Serkin, and I didn't like it, though I knew it was good. A good while later I heard Ashkenazy's performance and fell in love with it, and one day it will be in my repertoire.
But I wonder what I would have thought of these had I played them
before hearing anyone else?
