As a suggestion from the Eva Cassidy thread, I'm starting this as a separate discussion item.

There seem to be huge differences in how people hear the same voice. I'm a 58-year old male, and I really wonder if certain sound timbre and frequencies register differently with age and gender?? For instance I, and several other men I know, find Alison Krause's voice sexy and pleasing. A number of women I know deride her "little girl" sound. Do you think there is a difference in the way males & females discern voice quality?
