Removed the compilation Greatest Hits: My Prerogative list because the number was not published current (only 140,000 copies, and in the semen debut sold 255,000 copies, staying at # 4 on the Billboard chartitself). Despite the error, Spears has excellent numbers. Accounting for 32 million copies in albums. And 21million downloads in the singles.

Spears, Shania Twain and Mariah Carey are the only women that have emerged in the last twenty years have sold over 30 million copies in the country.

Remember that all numbers are only the United States.
