Umm wth? This is deeply sad. Not one of you have mentioned my gurl Crystal Kay in ur post especially the people who are R&B regulars. *cough* kobayashiwoofCelaphorce *cough* :cry

IMO, Crystal Kay has the best voice overall in Japan. Never have I seen this chick eff up in her live performances nor sound terrible when holding notes. Chick is always on point with her singing. So sad that she only got recognitized for like one year. BB girl needed more luff than that.

^I was going to say Crystal Kay...honestly I was, but I couldn't remember her name, lol Koi No Ochitara is prolly her best song imo and she has great vocals in it, I even forgot to add Mika Nakashima, Ayumi, BoA, so I feel terrible right now, but for Crystal Kay and BoA especially cause I LOVE BoA's ballads...:(

WOOT! Another Eri Nobuchika fan.
I can't believe I forgot to include KOKIA on my list. :thud

LOL

I'm sure many people believe that she is actually good at singing!
xDD

that makes it even funnier

MISIA all the way! :)

Mika Nakashima
Utada Hikaru
hitomi
and of course.. Ayu !

there's a lot!

Emyli, Utada Hikaru, Angela Aki, MISIA, Ayaka, KOKIA.. and Kumi.
(But I think that Kumi could give them more of herself, she has a powerful voice too!)

Well, then i'll say..

Ayaka ^^

oh! and Emi Hinouchi too.

She's soooo good ^^

MISIA because she has a really good, powerful voice.

hitomi because her voice may be a little different, but she is always flawless

ayu~!
and maybe namie amuro..very smooth <3

ayaka, Ayaka Hirahara, Yuna Ito, Utada Hikaru, Mika Nakashima, Seiko Matsuda and of course, Leah Dizon (just joking LOL)
