I guess ARTPOP will miss the number 1 now when Eminem sold 780K (!!!!!) this week and not so 725K he supposed to sell... he will fall to 350K +/-? this will be so CLOSE! Discount or something, I think everything is fair game (with everyone, not just gaga)
It should be more like 330k if the 2nd-week % drop is the same as Recovery.
