I listen to her without the videos a lot . I do a lot of stationary bike routines and if you want tenacious , relentless , high tempo eight counts her stuff is great .
She is only a performer though and not the creator of the material . I post a lot of videos by the group Perfume , they also do not create the material . Both may have a say or influence but the one person behind both is Yasutaka Nakata who is also the group Capsule .
Perfume is my favorite but I enjoy and use them all .
