I usually start people with what made me fall in love with Ayu:
No way to say
Memorial address (take 2 version)
About You
GAME
my name's WOMEN
Moments
CAROLS
INSPIRE
STEP you
is this LOVE?
alterna
Will
HEAVEN
fairyland
I figure if those are the songs that made me love her, then my friends with similar tastes as me will also like her for them.
Sometimes I'll throw a newer song or two in, but I usually dose them slowly over time. haha
