In reply to Mark111.

4 also made a profit. It was a chart topping album despite being leaked and went platinum unlike Artpop. Rated R has barely sold more than 4 even with 'hits' (I've forgotten what they are) It's still in the early 3 million area. Besides that's not the point, the point is you invested more in Talk that Trash and Unapologetic than you did Rated R and that album was far better body of work. So it's the same.
