hmmm as much as I think she's hot, I can't bear to listen to her:(
It's true, she has a bad case of what I call cartoon voice syndrome, or CVS. It's a very serious condition that renders something like 20% of Japanese women's voices unbearable to some people, while at the same absolutely irresistible to some men.
I happen to fall in the camp that finds it unbearable, though just to be clear I have nothing against those who have CVS fetishes. I totally get where you guys are coming from, I can see how it might appeal to you, it's just not for me.
I must say, though, that the music video does not sound at all like her usual voice, so I'm guessing they had a computer de-Mickey-Mouse-ify it. Actually, let me correct that: they probably would need at least three computers on that job. Supercomputers. Running at full capacity, mainframes almost melting.
I kid, I kid.
