1) Tomo- song is well paced, and Momu voices sound nice together, and they can na na na na na as well as any pop group anywhere, anytime
2)Fine Emotion- Miki Fujimoto has one of the most unique voices of all singers associated with H!P, and it has always blended well with any of the other strong singers, in this case Reina.
3)Aki Urara-play this in a disco 25 years from now, and all the dancers will easily be able to shake it, bake it, and fake it till they make it with this tune
4) Ai Takahashi is another one of the unique voices in H!P, and she can handle just about anything they give her, but this song has a pace that is difficult for her in this performance
