It's really, really hard for me to disrespect Kate Bush or her music. She is a profound genius who strives to say something very specific with each song of hers, almost as if she's engaging her audience in a conversation, so I guess I tire less easily listening to her music than to most artists because of that.
I'm a big fan of Imogen Heap who is very similar to Kate Bush in that she brings together technical sophistication in composition, a love of technology in the service of art, and something deep and meaningful to say in each song. It's hard to conceptualize that much awesome incarnate in a single person.
