Oh that explains it, I was wondering how they got a new studio album out in 6 months
That's sort of annoying...I hope Bump gets #1 but b-side collections aren't very popular in Japan, compared to bests which are super-duper popular typically. I'm almost positive B'z will reach #1 no doubt, but the question is with how much. I'll predict 350k. Their last one released less than 3 years ago sold 762,000 first week.
Sales are in! Single sales are up a lot today!
For singles:
x->1->1->1->1->3->3 - Glay - 26,436 + 13,897 + 5,005 + 3,559 + 2,720 + 4218 (x1.75) = 97,711
x->2->3->2->2->2->2 - Koda Kumi - 23,833 + 8,590 + 4,080 + 3,453 + 2,928 + 7269 (x1.75) = 87,767
