Help, what's the name of this song?

[Kevin B]

Whenever I'm out at trendy nightclubs I always hear this song that it seems everyone is playing right now. Any idea what it's called?

Here are some clues:
It's really mellow, i think it would be classified as house music
There's a woman singing in it, she speaks kind of quickly during the song so I can't really understand what she's saying.
But the chorus is clear, and she says something like "you never know when love will go your way" or "you never know when things won't go your way".
I'm not sure that's exactly what she says, in fact i might be totally wrong since I'm always drunk when I hear it. Can anyone help? sorry for the sketchy details.
