^ I as well don't really like to bother with the singles, since there's way too many (not to mention almost all the songs from her singles are featured on albums anyway, so it's kind of a waste of money unless you want remixes + instrumentals). I have collected a few here and there though:
For my dear
SEASONS
forgiveness
CAROLS
fairyland/alterna
Most of those were just gifts though
...
I only own three albums so far:
A Song for XX
LOVEppears
I am...
But I am really working towards buying all of the albums at the very least. I don't like to d/l, but since I like SO many J-artists it's too overwhelming to purchase every single/album from each one lol. I'm mainly focusing on Ayu at the moment though. Then I'll move onto Hikki and Kumi.
