* US sales receipts are above
* the WW album sales are from the UWC (Media Traffic)
* for some cases (Nicki Minaj, Carrie Underwood, Lana Del Rey and Kelly Clarkson) I used the receipts thread WW numbers
* Just female artists since 1998 because I don't have the official recepeis of Madonna, Whitney, Janet, Celine and Mariah (if you have them I'll add them)
* Shakira is missing because I didn't find her US album sales (if you have them I'll add her)
* If I'm missing anyone just tell me!
Why is this?
Never thought Hilary Duff was so big
