of Pop of course
King:
Michael Jackson
Why? He's never lost his title because he has over 10+ #1 hits including Thriller and until Usher breaks that he will be the king of pop. He's also been in the music business for about 30 years I believe.
13 #1 hits
Queen:
Madonna
Why? She gave us Like A Virgin, Holiday, Speed of Light and even Hung Up she's still in the music business with a slew of #1 albums and hits and she's been in the music business for nearly 30 years.
12 #1 hits
Prince:
Usher
Why? Heck he started when he was like 14 (take that Chris Brown) and 18 is when he started making #1 hits with Nice and Slow off of My Way, then he released 8701 which represents how long he's been in the music business and off that album he put out like a story of songs that all made sense like U Remind Me and U Got It Bad which both made it easily to the top spot. Then he put out Confessions which made him earn this title selling not only 1.1 million copies in it's 1st week but he got 4 #1 singles (Yeah, Burn, Confessions Pt 2 and My Boo with Alicia Keys) off this one and now his album is certified diamond. He's put out 7 #1 hits and his looking to make a huge comeback this year and as long as he works with Jermaine Dupri he should be okay and perhaps he might eventually be the king of pop. He's been in the music business for 20 years!
7 #1 hits needs 7 more to break his record and become the king of pop
Princess:
Mariah Carey
Like Usher she's been around for 20 years and like Usher she's put out many #1 hits only more including Fantasy, Honey, Heartbreaker, One Sweet Day and even We Belong Together which she made recently a couple years ago and it was the biggest single of 2005. Like Confessions, The Emancipation of M.I.M.I. was huge along with many albums she released. She was recently featured on Bone Thugs N Harmony song Lil L.O.V.E. and it shows she's still got it and in a couple of years she will probably be the queen of pop.
17 #1 hits!
