BTW, If anyone is interested in listening to an epic RnB Japanese album I highly recommend "Renai Chuudoku" by Mao Denda. It consists of 12 love songs composed, arranged, and written by Denda herself. The album is flawless from start to finish and I've been hooked on it for the past month.
There are some short PV of some of the songs on youtube if you guys are interested:
It is kinda funny about Hikki's sales... but I do feel bad for her. Ayumi, Kumi and Namie have never taken a long break like Hikki has, the longer break you take the quicker you seem to fade.
