Can't really tell anything from the preview... The song could drive in a Perfume direction, or POP DIVA or even Namie's Heaven. Need moar to judge it properly.
So, Bring it on ain't the a-side, uh? Hopefully it won't be the b-side also, cause if it makes to the album it may get a PV
It had a nice dance routine in that perfomance, I'd love to see Kuu dancing to the whole thing
