I think she has had some ups and downs vocally
like 1998 - 2000 she sounded well... it wasnt WOW
and then 2001 - 2002 she sounded amazing
tour of secret was incredible but then later with talkin 2 myself and stuff
it was just something I didnt want to hear and I think after the Mirrorcle World
lives she started improving much again. AT 08 was already so much better than CDL 07-08.
and then when she sang SEASONS and Days live at FNS I think she sounded great.
and well @ PCDL her vocals were pretty damn good in my not so humble opinion
it was something I actually really enjoyed watching.
and a-nation this year was just as good +++ plus AT 09 what I've seen sounded
pretty nice tho it wasnt perfect all the time.
