Hm, you know. I don't like any men's voices. xD I'd still want P!nk's voice even though I'm a guy. <3
My favorite voice to listen to is Gwen Stefani's, definitely. But for me... Probably Johnny Cash. He doesn't have a huge range, but he sounds awesome. And I like singing low.
If I was female it would have to be easy - Karen Carpenter. As I'm male I'm not quite so sure. Freddy Mercury perhaps?
Idina menzel (from rent, wicked, aida, ect... all the great musicals) and if i was a guy - josh groban.
Kelly Clarkson. But I'd rather have a guy's voice (even though I'm a girl I'm more in love with guys voices) and I'd pick Clay Aiken (goddamn that man can sing) or Nick Thomas.
Alex Kapranos of Franz Ferdinand has a pretty cool voice, as does Eddie Vedder of Pearl Jam, Freddie Mercury, and James Russell Mercer of The Shins But for myself I'd prefer to have a deeper voice like the former
If I was female I would want Cherie Curries voice; just because it's totally different and full of awesomeness. Think glam-punk. And as for a guy voice? I don't really like male singers... But probably Morrisey.
