I'm the youngest of 4 and my older brothers and sister listened to "California Rock". Eagles, Warren Zevon, Ronstadt, Fleetwood Mac, Jackson Browne.
Ronstadt had a great voice but only did cover songs, which lessens her stature to me.
My vote for greatest female voice of all time goes to Ann Wilson of Heart. Unreal pipes and could sing pop, rock, 70's metal and folk with equal ease. Unreal pipes on her.
