Need suggestions: High pitched female singers

I could use some suggestions of female singers with high pitched voices. I enjoy making ‘Best of’ CD’s and this is the latest one I’m working on.

So far I have:

Kate Bush
Sabrina Carpenter
Bif Naked  
Missing Persons
Teresa Brewer
Nancy Griffith
Asteroids Galaxy Tour
Millie Small
Viva Voce
Kasey Chambers
Yolandi Visser
Blossom Dearie
