My Seiko Matsuda CD collection is kind of lacking at the moment.
I have We Are Love and Was It The Future. I would LOVE to have Citron and Precious Moment as well.
I admittedly have not heard every single album of her's but of the ones that I have heard I loved We Are Love the most. Citron is great too along with Windy Shadow. There is just too many.

What I do is I just randomly buy or listen to her albums since there are just so many.
