im not familiar with everyhting by him but one of the most beautiful songs of the top of my head is nocturne
also scarboro fair and [Claire de Lune]
You know what? That is a beautiful song (C.d.L.) but after playing it a zillion times on the piano growing up, for some reason I don't love it the way I used to. What's weird is that no amount of playing Mozart ever tires me of him.
