Ok this is out of my camp, but this 30-song 2-CD greatest hits album of singer Crystal Kay (Wikipedia) will contain a new song by Nakata Yasutaka (capsule, Perfume), only on a bonus 3rd disc in the limited edition. Other new songs produced by Taku Takahashi (m-flo) and others will be included.
Crystal Kay "Best of Crystal Kay"
1. Over and Over (produced by Taku Takahashi)
2. Step by Step (produced by Nakata Yasutaka)
