Oh Ayu... I don't like her cutesy voice, neither while singing nor speaking (although speaking is much, much worse, cause singing is part of a performance after all).
I listended to the live recordings truhappiness posted and I was literally dying trough the first words of rollin'. XD
It sounds horrible, but somehow it is fascinating to me at the same time this time, it's weird. XD
If rollin' is really such a funny and strange performance I'll love it, cause I love weird things (and the cutesy voice fits then).
And by the way rollin' is with Sparkle my fav song from NEXT LEVEL.
