Some of the tracks on MY STORY were accidents. And also, it helped that she didn't feel right that Memorial address had to end up being a mini, so she spent extra time on MY STORY that she normally wouldn't for an album. I think for me, I've just let go of most feelings I had for albums that were 'big' for me in her 'golden years' and just think of each album as its own entity in a different stage of Ayu's career. Like we know that Secret and LOVE again were sort of heavy on 'leftovers', but I don't think that really makes them bad albums especially if you actually listen to them from start to finish more than a few times.

However, imageshack resized all of the images so they are almost illegible now.
Oh thank goodness, I saved one of them.
