Excuse me? Kelis has been out there since forever. How can we forget the all the time classic "Caught Out There" ? Yes it didn't go Top 40 but it's still memorable. More than anything in the Top 10 nowadays. 'Milkshake" was a hit and "Bossy" peaked at number 16. She is definitely NOT a one hit wonder.
Plus she's had other hits overseas. People are always quick to talk **** about Kelis
Love Her Music 
Hope She's Not Been Dropped In The UK
