but it's saving more energy if you're not dancing and singing at the same time though..
maybe as for Ayu, she wants to show best choreographer and acting when comes to up beat songs?
or probably... Ayu was not used to sing and dance at the same time in her earlier days, therefore, in her recent performances where she needs to dance, she is kinda lacked of energy for that, even though she can train well, but with her hectic schedule like that, i doubt she can do that~ and she's definitely not a pro for being a singer who can dance and sing at the same time..that's why she uses playback in some songs?
i think dancing is like new to her.. where she's supposed to be just like Hikki who only explores in music and singing.. where Ayu wants to conquer all? hahaha lol
