I think SEASONS is one of her best songs lyrically.. she did win an award for the lyrics to that song. It's a pretty good song to analyze, and its easy for people to relate to =P

oh yeah yeah... Curtain call's not bad too~

A Song for XX definitely!

Endless Sorrow for sure.
Fated
RAINBOW
M
HEAVEN
Memorial Address
part of Me
Because of You
Fairyland

and even I'd say Mirrorcle World.

HANABI! JEWEL! SEASONS! ASFXX! END ROLL! ENDLESS SORROW!
These are really really poetic! They're rly good lyrics too. Amazing Ayu~~

Mirrorcle World.
evolution

I think so. :D
