Madonna sold more but had a longer time to sell it mariah sold 130 million by the time the 90s ended she may not be the best but she certainly is the fastest and another thing she has the most #1s by a solo artist period and spent more weeks at number one than any other artist in the history of recorded music if you think people didn't buy those you are sadly mistaken!I love Madonna but her stans need to sit. Like mariah hasnt broken or made any record her net worth is outrageous she's just now getting endorsements. She made her money solely off of her music....anyway Mimi making me wait 2 more months:(
