Mariah doesnt have a big pop culture presense like Madonna does. Mariah didnt change music, she is just a really great singer. She was Queen of the 90s perhaps but other than that her impact and influence is very limited.
Madonna is the Queen of Pop and no one is taking that spot. No one. The princesses of pop after her are Britney Spears and Janet Jackson, they were the only 2 real viable competitors to Madonna when they were at their prime.
Gaga is too new to even be in this equation. She doesnt even have a decade in the business yet people are quick to crown her with something. She is just a phenomenon for now
Replace Janet with Kyle, Janet's music has never been full Pop either
