Alabama Shakes, Evanescence, Adele, Stevie Nicks, Alecia Keyes.

Aretha, Amy Winehouse, Adele.

2 of the all time best female singers are bonnie raiitt ,check out her verizon of (I can't make you love me)
and lucinda wiliiams (check out the songs car wheels on a gravel road & these 3 days)

My favorite is Ella Fitzgerald.

Janis Joplin has some real smooth southern comfort spirit in her presentation Barbara Striesand was one of my all time favorites.

Oh, and I love Ute Lemper, too. Her album of cabaret songs from 1920s Berlin is a masterpiece, as are her other recording, esp. "Punishing Kiss" and her rendition of songs from Brecht/Weil's "Three Penny Opera."

June Tabor. English folk/artsong singer. Performed with Maddie Prior (of Steeleye Span) as "Silly Sisters," and with the Oyster Band (Her rendition of Grace Slick's "White Rabbit" is amazing.) Sings many songs from and about WW I (one of the first people to record Eric Bogle's "The Band Played Waltzing Matilda" and his "The Green Fields of France," ) did a album of 1940s jazz standards. Does humorous songs, like Les Barker's "Oh, the Hard Cheese of Old England," and fantastic renditions of Richard Thompson songs. Once you've heard her, no one else can compare. She gently rips your heart out.

Oh come on Britney Speers and the rest of those plastic dolls. Real singers Ella Fitzgerald, Billy Holiday,Aretha Franklin, Carole King ( who wrote her own songs) Jonny Mitchell ditto, Shirley Bassy, Dusty Springfield, Janice Joplin ( who sang haer heart out).... err I think you can tell how old I am. LOL. Oh forgot Doris Day, have a serious crush on her.
