What would you think if I sang out of tune?

It turns me on when a woman can sing a tune, but the truth is that I would rather be with someone that I am attracted to mentally, emotionally, and physically. I don't really care if my woman can sing or not, just as long as she has other qualities I'm looking for.

Everyone who likes music enjoys a good singing voice.

What I would have a problem with is if the person in question became "scary" when singing. I saw an episode of some late-night program, where Fiona Apple was the musical guest. She had this hungry, and quite offsetting look on her face when she really got into the performance. I like the albums I have of hers, but I don't think I'll ever go pay to see her in concert.

If singing were a passion for the woman I was with, although maybe contradictory of me to say so, I would think it a sign of affection that she shares it with me.

Any talented voice is pretty (and impressive that she would be dedicated enough to develop her natural talents).

A bad one can be funny. ("We both sound like dying cats. Amazing! ")

Any one she's confident enough to share is a plus. So long as she doesn't expect to be taken too seriously (Even if she sings at the Sydney Opera House, if she's belting out "I'm A Little Teapot" in the shower, I'm going to crack up. :P)

Vocal talent can be attractive. But unless the guy is seriously uptight about music or something, no one find singing out of tune a turn off. Personally, I find it kind of cute when a girl sings out of tune once in a while. And hey, at least you try to sing in front of people. It takes courage to do that.

It can be. But a singing voice is a bonus, and not the selling point.
