Meanwhile no one cares because any person with even an average IQ would know that comparing an artist who debuted in the 90's to an artist whose first release was at the turn of the 10's decade is stupid. Aren't Gaga's adjusted sales equal to or more than Methney's? hihi
No they are not.
I think it's around 65m for Gaga and just over a 100m for Britney
