I appreciate Matsui for having actual musical talent. Getting a solo piano album is really awesome and an amazing chance for her. I don't really see Sakiko as an idol. She seems to classy and composed for it. On the other hand, is there are people learning an instrument they might look up to her and apire to become like her. I guess she is an idol in that sense. I'm glad to have her on board and I hope she'll get to use her skills in a cool A7 song.
