Yeah, it is! It only plays in the movie once but it sounds nice xD
I really like Princess Mononoke too but I always get so frustrated when I watch it (The first time I saw it I was crying-- LITERALLY-- from how greedy everyone was being). I think my favorite Ghibli movie has to be Laputa. It's a nice, light-hearted adventure movie where I don't get frustrated at the characters haha.
And it's so conflicting since none of the characters are truly inherently evil. Lady Eboshi is kind and sweet, but she's just... super greed u n u;
