i'd say Ailyn from
Sirenia (it's because of their song "Oscura Realidad," it's so lovely in a strange way, if you know what i mean.)
also Sharon del Adel from
Within Temptation ("Jillian" is just great. she frequently uses falsettos, though.)
Ji-In Cho from
Krypteria (when i listened to their song "Deny" i've come to believe she has a great potential. i think they should switch their style to
Industrial Metal, though.)
Jyou from Exist Trace (i dunno, she's so cool when she growls.)
Amy Lee from
Evanescence (no falsettos. simply amazing.)
Otep Shamaya (LUUUUUUUURVE her growls.)
Aya Stefanowicz from
UnSun (she sounds like a real Snow Queen.)
and of course Cristina Scabbia from
Lacuna Coil (i dunno. she's simply amazing and she seems to really know what she's doing. i mean, have you listened to their song "Leaving Alone?")
"you're missing the big picture."
