Maybe she'll release it a week before the VMAs. She would get a full week of sales and then the VMAs come around and she has a second huge week.
Now that I think about it though, August 4th would be perfect:
1st week: First week of sales.
2nd week: The Giver promo.
3rd week: nothing in particular.
4th week: Another boost from the VMAs.
A new song I heard today "It's a Long Way Home" the best Ive ever heard from her vocally and lyrically. Plus I heard there's a new blog coming very soon
