Who are your three favorite female singers?

These are my favorite female singers --
Ariana Grande
Selena Gomez
Rihanna

I’d like to think the OP question is which female voices give you goosebumps when you hear them.
so for me it rules out some previous poster’s choices where I find limitations in the singer’s abilities. For instance, Sade has a great voice but her range is so limited every time I hear her avoiding a high note by going subdued it just ruins it.
as far as Joni Mitchell and Joan Baez, they just do anything for me (great songwriting, I’m just focusing on the voice). Picking them is like picking Neil Young as great male singer.
for range and ability to sound golden, soft, harsh and use pitch nuance I find Barbra Streisand and KD Lang just have it.  to me KD Lang is a female Version of Bono’s voice.  
Third choice is rather hard, I’d have to say Diana Ross.
on a side note, nobody could argue that Cher is one the the greatest female singers....but nobody’s favorite!  Popularity -  yes.  Goosebumps - no.

Lots I like but these 3 are getting the most play lately:

Ely Bruna
Janiva Magness
Inger Marie Gunderson  ( similar style but prefer her to the ubiquitous Diana Krall)

@fleschler
I’m with you on JERI SOUTHERN and DINAH WASHINGTON.

Glad to hear that you’ve given STACEY KENT a chance too. After years of listening to her, I’m still totally enamoured with what MS. KENT can do with her little voice...

In hindsight, it was remiss of me to leave JULIE LONDON off my larger list, also.

Thanks to all.  So many great thoughts and female singers.  Thanks also for adding June Christy
