at all the people who've already bought the album. In today's climate, it's important to wait half a year to a year and than decide to buy an album, so you can directly buy the version with most songs.
Seems like many people haven't checked that or how come so many albums are selling so frontloaded
Me, I haven't bought the album yet but I'll wait how it'll develop.
I just wonder that its sales are relative low. It hasn't even reached Multiplatinum-status yet. Super Bass also didn't really do that much for the album. Singles selling albums can make their mother album return to the top 10/20 (best example: Loud in France after Man Down reached No. 1 there). Considering all the backgrounds, Pink Friday could be between 2 and 3 mio. with ease.
Perhaps many people knew that there would be a re-release and so waited with a buy!
