Folks - to clear the confusion -
Sales for the Billboard chart are based on units sold - regardless of the number of discs within a package. So reports of possibly 80,000 units is precisely that - 80,000 sales.
Certifications for Gold Awards etc.. are then based on the discs within a package 1CD = 1; 2CD set = 2 etc.
Good number then for the band...80,000 first week would be great.
I will present the EXACT number sold early next week when 100% final.
