Song with Piano Techno/Trance/Eurodance with a piano beat?

Hi i was listening to the radio and heard a piano melody that keeps playing over and over and gets a little louder every time with no trance or techno in it just the piano beat. then towards the end of the song it becomes more of a trance/techno song. anyone know the name of it (I also heard it in a club so i know its kind of popular) anyways its not robert miles child I know that song. Anyways any help would be great thanks
