i love the "oldies but goldies" like Ella Fitzgerald, Aretha Franklin, Billie Holiday, Sarah Vaughan, Gladys Knight, Nina Simone, Etta James, Dinah Washington, Tina Turner, Chaka Khan, Patti LaBelle and so on, but from the list i have to choose Whitney, at the pick of her voice (early 90's) she had the most beautiful voice to ever record a song

Aaliyah
