Its female artists BMR and the voice is somewhat horses for courses and without doubt many look as the songs , bands if appropriate , sound , and even some more specifically have ears tuned into more alto than soprano if if comes to sound and quality of voice.I honestly can't understand how Debbie Harry can finish top 3. Ok, she was decent and I liked Blondie's pop punk sound at the time but her voice ain't that good IMO.
I didn't even vote for her FWIW.
I like all types in all ranges perhaps outside classic mezzo soprano if done well with a leaning to alto.
then there is your eyes and there is little doubt for most red blooded males for example Kate , Debra and a youngish Joni would invoke some pictures of lily if you liked your female songstresses in your formative years and beyond.
Sex appeal or did I forget that bit.
Who didn't think KB was singing to them when she belted out babooshka despite the storyline told.
