i think there will be many artists:
Michael Jackson
he isn't my favourite anyway... but he's the king of pop...
Elvis
the king of hips ^^
i think all of u know him, but he's death for a long time now...
Madonna
i really don't like her (except the one or the other song)
but she really is a legend now...
she isn't the prettiest anyway...
her music and her carrier count i think ^^
Britney Spears and/or christina aguiliera
i think they're one of the best the world have ever seen...
forgot the silly things britney did...
i think only about carrier and music
Lady GaGa
I'm not sure, because her carrier wasn't so long actually,
but i think if she suprise the world again and again, over a long timeline,
she'll be a legend too ^^
The Beatles
who don't know them?
i think about
Take That too..., but i'm not sure about this ^^
yeah~
