^I'm just comparing quantity... I don't think there's anything wrong with that, considering both of them are constant on media nowadays... They didn't released as much as Utada, still, I can see some people saying they should take a break (as I already saw). I just wanted to show that for western music, she is releasing at a very good pace
If we can't compare to those, we can't compare Hikki releases to Ayu's. Seiko's or Koda's too, considering that even to japanese standarts they release too much material...
But ok, Utada released almost as much as Namie (don't know who released more), still, nobody calls Namie lazy

Namie goes on touring every year, but she almost never composes, while Utada does compose/produces/arranges...
