I still don't get where the flop is
If it doesn't sell a million it doesn't mean it flops, specially not just because the sales dropped.
I just can't see albums that sell over half a million called flops. Specially not when they sell it in a week or a week and few days.
What are those exaggarations? A COMPLETE ~ALL SINGLES~ is doing pretty well even with the drops.
It's not like it sold 50,000 or 100,000 in 3 days.
Most albums (even compilations) don't reach even close to that.
