Yes but I think your missing the point they sold poorly but did not underperform. It was the case with all big name artist that performance did not equate sales. Much like how in 2013 an album could be top 20 for half the year yet still only scrape a fraction of what they would have even 2 years earlier was it a flop did it underperform no sales fluctuate always have always will.
And why is her continuing to strive for success desperate at this point in her career. I think it's great to see someone after 25 years and all that she has achieved strive to outdo and better herself she's not dead yet and neither is her career.
I have to agree. Adding to that I have always felt her attitude towards the US has always seemed half hearted. If she really wanted US success she would have gone over for a year or so really working hard to establish herself there. A few weeks here and there will not get her US success, she'd need to start from scratch which I'm sure she would not be willing to do.
