Music similar to “The Girl From The Other Side”?

I really like the music for the movie and the ova. Especially the track that is playing in the background of the OVA trailer. It has a whimsical, fairy tale ish vibe to it. It is so sad, that there is no official soundtrack for it …

So I was wondering if any of you know of soundtracks that have a similar whimsical vibe?
