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.
If you like both of those artists, I'd suggest checking out Kimbra. She has heavy jazz influences and incorporates so much meaning into her music and videos. She does similar vocal layering to Imogen Heap and her live mixing of her own vocals is simply amazing.
Oklou's album "Galore" might also appeal to an Imogen Heap fan, with interesting self-made layering of vocals, electronica, some cathartic moments, and the videos are pretty darn good too.
I mean, there are a lot of artists whose fandom can say the same thing. I might feel the same way about Joe Strummer, or Glenn Mercer from the Feelies, or Elliot Smith. I'm not saying you're wrong, I'm just saying it's all pretty subjective. I don't actively dislike Kate Bush, but I'm not tuned into her the way you are, and so I get different vibes from her songs than you do --- like I said elsewhere on the thread, she has big-time Tina Belcher energy for me. I think the snowman song ruined me for her.
