Globally:
No specific Order.
-Shakira
(The one with the biggest trajectory in this thread, not that popular right now in the States and the UK because released a spanish album, but HUGE everywhere else, even in Africa's most remote tribe town.

)
-Gaga
Very successful debut album, popular everywhere, but with this second album she lost some popularity when it comes to a really global basis. Will she survive with the next album?
-Rihanna
Very successful artist. Some markets still need to be conquered but still a career with huge achievements.
Bonus:
-Britney and Beyonce
