Kimi Sae was really good! i liked it! Ayumi needs singing classes and she will be a master! she really need it, SHES GREAT! she's in tune only needs to control her diaphragm, and thats all
I never liked Mizuki, i don't know why so many people says she is a great singer while she is obviously not, and i am pretty sure her version of aruiteru has been recorded before?, its not fair because Airi's and Kanyon's versions were live.
Ayaka!!!! she is so beautiful definitely a tv girl.
I don't think Mizuki is a bad singer, but I definitely think she has a limited range. But she's hardly the only one right now.
