12. Madonna
Katy and Taylor can try all they want, but no one will ever steal the title of Madonna’s eternal Queen of Pop status — she has 300 million sales, making her the queen of this list. Year after year, she’s served us hits, starting back in 1982. Unbelievably, her album “True Blue” earned #1 in 28 nations, but her most esteemed work is “The immaculate Collection”.
