Beyonce already is one.. if Britney isn't on this list, than she shouldn't be either.
Lady GaGa has already done so much stuff in so little time.. I know she won't be going anywhere anytime soon.. she's done things that Bey, Britney, and all the other legends have not done, and in some ways, not even been close to doing. Ever since 'Just Dance' went #1 on Billboard Hot 100, she's been on top. She's not coming down for a
LONGGG while.
Justin Bieber?
Hopefully he'll be gone soon, he's already been here for too long.
Katy Perry is great in singles, but in the other areas in music (awards, albums, etc.) she isn't as much.
Rihanna has great single sales and album sales, very popular. She'd definitely be the 3rd best choice.
Taylor Swift would be 4th, she's done 1 million albums, she has so many loyal fans, she loves what she does and it seems like she won't be stopping anytime even CLOSE to soon.
Ciara.. oh come on, don't put her in this poll as a joke.
That's harsh.
Ke$ha, though I love her, seems like a fad to most people. She could probably still be huge with the hit pop dance singles she puts out but I can see people getting over her at some time.
