It's so easy to think of guys with quality voices.
To me male artists just have such a soulful and amazing sound.
It's hard for me to pick females.
I think Christina Aguilera has a great, strong voice..other than that I find it hard to pick girls because they always seem so synthesized and fake.
Michael Buble has a wonderful voice. I enjoy his version of What A Wonderful World. He has a cute, classic but kind of modern voice. He sounds charming on piano.
John Mayer and Jack Johnson have very mellow voices, their voices calm me.
No comment on females. There are tons of talented ones out there, but I don't really care for them.
