Your favorite male/female singer

[fable]

Male: Tito Schipa. Great singer of opera and Spanish, Italian song back in the 1920s and 1930s. Incredible stylist.

Female: Billie Holiday. Jazz singer at her best in the 1930s and 1940s. IMO, nobody has ever touched her way of phrasing and her ability to put so much "face" in the words.

[Mr. Pastorius]

Male: Frank Sinatra, Freddie Mercury, Bono Vox, Maynard James Keenan
Female: Aretha Franklin, Billie Holiday, Joss Stone

I've put more than one person because each of these vocalists differs from the other one, either by style or his/her approach to singing.

Male: 1st Hansi from Blind Guardian(the best voice), 2nd the jens carlsson from persuader and savag circus(a nice Heavy/Power metal voice).and the singer from stonegard(norwagian band)
Female: 1st Amy Lee from Evanescence, 2nd Simone Simons from Epica.
