Your statement of Madonna being the highest selling artist of all time or in history is false. Madonna has done between 300-370 million.

Michael Jackson has 350-750 million.

Elvis Presley 600-1 billion.

So Madonna has sold more than these two in HISTORY? I think not.

Madonna has the record for world's top selling FEMALE recording artist of all time, not everyone. So once again take your own advice and check your facts.

By the way, Invincible is 2x platinum, Greatest hits is 3x platinum, and other random albums released after Dangerous are between gold and platinum.

Do research to see that Madonna has not out sold Michael, Elvis, or even the damn Beatles for that matter.
