I'm in love with Youko Kanno! =O
I especially like her work with Maaya Sakamoto, and Cowboy Bebop and Wolf's Rain may have my favorite soundtracks by her! As for Kajiura, I haven't heard nearly as much of her music, and she didn't leave me with the same kind of impression that Kanno did the first time I heard her music. =D
I know that Kanno has done a few. Napple Tale comes to mind.
