oh yeah here is her blog translated to english too if you dont know
Hikki's blog

I wouldn't categorise move as Jrock. Those who say they are Jrock have either heard very little or only heard their newer songs.
They've been around for 10 years and anyone who has gone through their discography knows that they've done more than just rock. Hell...they even have more non-rock songs. And there really isn't any other group that sounds and has done as much variety as them.

any hikki fan has to listen to her cover versions of

1.i love you(by yutaka ozaki)(it:s not the song in  deep river, i think its tht one)

it was only sung live in one of her concerts but she showed he vocals, even more than in final distance or first love. she never agreed to do a studio version after that because she liked the live version alot. and btw, i love you is the no.1 song in oricon:s top 100 love song. first love was no.2.

2.shounen jidai(inoue yasue sang the original)

she did this in a radio interview and it:s a pretty nice song, a very nice update of a popular song

my favourite hikki songs are

first love
distance/final distance
flavor of life
wait and see
addicted to you
can you keep a secret
fly me to the moon(her only english song that i like)

i:m waiting for her new single, seems good

i'm listenin:
L'Arc~en~Ciel
