Stevie Nicks has a quality in her voice that I really like. I can’t quantify what exactly it is, but I do like her voice.

I think her voice has an edge, almost a percussive quality, similar to that of Kenny Loggins.

Which is probably why they were paired into the duet Whenever I Call You Friend, back in 1978. That song really displays the similarities in their two voices.

Others with that edge are Curt Smith of Tears For Fears, as well as Judy Garland and Liza Minnelli.
