"Till the World Ends" {...}

Eu sei quem canta isto...a sério que sei...mas tenho andado com esta música na cabeça...
"I can't take it, take it, take no more
Never felt like, felt like, felt like this before
Come on get me, get me on the floor
(...) what you waiting for?"
"IF YOU FEEL IT, LET IT HAPPEN
Keep on dancing til the world ends"
