^Well it will most likely drop out of top 10 tomorrow and end up in the 15 to 20 range for the weekly position (which is what happen to Catch the Rainbow, with popularity that roughly match Aitakute Ima)
Well with her recent sales, i think maintaining a first week sales in the 70k range (which is compariable to her last 2 album) would be a good enough sales for her, after taking into account the declining music industry. I would expect namie to easily sell 300k of her latest album within the 1st week

shouldn't be a problem for her
