Oh, yay!! I love these
a song for xx: a song for xx / poker face
LOVEppears: Fly High / Who...
Duty: Duty / SURREAL
I am...: still alone / M
RAINBOW: Dolls / Voyage
A BALLADS: Dearest / Dolls (again)
Memorial address: Memorial address / HANABI ~episode II~
MY STORY: Moments / GAME
(miss)understood: alterna / momentum
Secret: Startin' / kiss o'kill
It's really hard for me to choose these: I am... is my favorite album by her, everrr, with Duty as a close second. MY STORY and Secret both had to grow on me as far as albums go, but the songs chosen are the ones that really hit me the first time I listened to 'em. A lot of the songs I chose not only are my favorites, but either are very close to my heart or hit me REALLY hard when I first heard them/read the lyrics. Some of these songs are responsible for me getting into Ayu in the first place.
And I'm aware the some choices are both singles

Sorry 'bout that. ASFXX doesn't really impress me much, apart from those two songs.
