^ In December/November. Just wait until the release of the new Ken Hirai single
It will be hyped up by the release of his best album. It's the biggest release I see with Mai Kuraki, Morning Musume, Hikaru Utada, ELT and aiko. And they don't sell that big (Ken and Hikaru do though). Most of these artists will release in November, except Hikki who releases Passion in December.
