Avex needs to take a lesson from Kuu. They pimped her out for all she was worth and then everything post-BC started to bomb. Over-saturation is very real!

EDIT:


SINGLES
x->1->1->2->3 - The Alfee - 6,152 + 4,588 + 2,636 + 1,489 (x1.75) = 26,014
1->4->3->1->1 - Amuro Namie - 3,290 + *** + 2,905 + 3,564 + 2,215 (x1.75) = 20,955 (excluding day 2)

ALBUMS
x->1->1->1->1 - Utada Hikaru - 67,698 + 64,284 + 50,958 + 27,386 (x1.7) = 357,554
1->2->2->2->2 - Shibasaki Kou - 7,597 + 11,008 + 10,682 + 13,070 + 7,077 (x1.7) = 86,510

Hikki took a huge drop... Weird. And it's sooo close for Namie! She'll probably get the #1 at this rate.
