Of course, the biggest Female album of all time is Whitney Houston The bodyguard which has sold over 45 million copies world wide. 21 Has sold around 30 million albums in a worse sales climate. If you adjust for the 90's sales climate. 21 would had sold over 50 million albums

( i can't find the receipt but it was a table showing how much albums from the 2010's would had sold in the 90's) so does that mean that 21 is the biggest female of all time if we adjust for inflation/sales climate
