You have failed to provide the proof but asked for 10 sources? I gave you mine! For easier finding, go to your obese Mariah's albums discography and simply click IPFI of the overall albums sales number and list! There you have it.  

 You are such a joke! And you are not making it any different! You are the one who says the same thing over and over again like Mariah sings! 

 Again, Mariah can take one billion of the POLITICAL World Music Awards without being based on the facts! It's nothing! And her record company can say that she may have sold 1 trillion albums in your dream world by becoming the best selling! 

 in this real world, Madonna remains the best selling female artist of all time! And Nana is right behind! Mariah is short of 40 mill albums behind Madonna's! She hasn't come close! so wait and keep following and watching Madonna's exhilarating ride! 

 Deal with it! And don't forget to do your homework, poor Mariah maniac!
