Best pop female vocalists

Honestly I like every one of those listed above but my God...

KATE BUSH

She has the best voice I have ever heard. And Elton John agrees with me.

Enya is of course off the list because she is far too poppy and way too many old folks like her and her instrumentals got way to popular unlike her first stuff. This is what I find interesting because of the drive to find the obscure instead of just breaking down and admitting yes this girl is damn good but too many people like her.

So now I ask quite sincerely, has anyone heard Kate Bush or is she just a little too British and too weird? So that I am doing exactly what I stated above...

Oh yes. I cant take Janis Joplin. I know there is a lot of feeling in what she sings but her voice kills me. Yet Tina Turner is captivating... I even like the Thunderdome song.
