(E) Doris Day
This. Surprised that took so long.
Carey deserves to be on the list, and probably not anyone else. So my list:
Mariah Carey
Patsy Cline
Reba McIntyre
Doris Day
LeAnn Rimes
Linda Rondstadt (have to agree)
Karen Carpenter (also agree)
Grace Slick (also agree)
Mary Travers (no one mentioned her?!)
Ella Fitzgerald (also agree)
