Who did the song with lyrics containing something like "straight to one"?

There was a popular song quite a while back, and I just can't remember who did it. It's sung by a woman with a breathy, y voice, and she's doing a countdown like "five ... blah blah blah," "four ... blah blah, blah," and so on, with the punch line being something like "straight to one." I know this is an easy one! Help me out!
