Janet Jackson is the Queen of Pop! The Queen should be someone who can appeal to more than the mainstream. Janet Jackson is the ONLY diva out of Madonna, Whitney and Mariah who was able to appeal to an MTV / video generation, R&B, Pop, and Dance - across the board.

Madonna is the queen of mainstream-pop yes, but I believe the Queen of Pop is more than just Mainstream, and Janet Jackson was/is that. Clearly, she scored 5 back to back #1 studios albums in an era when albums actually SOLD. Even in Madonna's peak, she couldn't score even score 4 back to back #1 albums.
