Oh! I love this thread. Makes me feel less alone. I'm with Jim and others -- it's the way the voice is used that makes that horrible breathy, sensitive, endless-song singing style.
I have a voice that hasn't changed since childhood -- soprano and young-sounding at 65. It's strong and out-there though and I never, never do breathy. If a song affects me while I'm singing I might cry but I don't become a little girl.
Cheers, Joy
