What is the name of this song and artist?

Whilst at the gym i keep hearing this song and i want to know what it is called. i've tried searching it on youtube but getting nowhere! It sounds like an old song remixed with a bit of rap. I cant catch what or any of the words the woman is singing because it is very tinny on there cd player but it sounds like rainnnn or fameee? please please please if anyone has a clue please let me know.
