This is in response to the album sales of Britney Spears and Christina Aguilera. The real sales aren’t close to what you guys thought. They are kind of disappointing far less than anybody thought. I personally wrote to United world chart and got the right numbers.
Christina Aguilera’s ‘Stripped’ has sold 7.1 million copies to date and Britney Spears’ ‘In The Zone’ has sold 4.8 million units so far in worldwide sales.
