Now I don't feel so bad! I love Ayu dearly but I haven't been able to afford her whole discography. I basically only listen to her singles and not album only tracks, for a couple I've heard a couple second clips but, here's a list; songs in bold are the ones I'm ashamed of not having listened to (

):
A Song for xx, Hana, Friend, Friend II, Wishing, As if..., Powder Snow, Signal, From your Letter, Present,
Trauma, And then,
immature, End roll, P.S II,
Whatever,
Too late,
Love: refrain, Staring over,
Duty,
vogue, End of the world,
SCAR, teddy bear, Key, Girlish,
I am..., Connected, Naturally,
never ever, still alone, No more words, flower garden, everlasting dream, we wish,
heartplace, over, Everywhere nowhere,
July 1st, Dolls, Close to you,
+... OK YOU GET THE PICTURE.
