Interesting points there, GfS. I think Stan Rogers was a very good male vocalist who got the most out of his voice...nothing "breathy" about Stan.

Stevie Nicks is a good singer in some respects...but she does not pronounce the words distinctly. Rather, she seems to blur the consonants and meld one thing to the next in a dreamy fashion and everything gets fuzzy and indistinct, so you can sometimes hardly even make out the words. I could never figure why she would do that. It doesn't help one bit in getting the words across to the listener. In other respects, however, I like her singing fine.
