Csi

Please does anyone know the song used for the commercial of csi vegas last night.It was a girl ,the song was slow and I know she kept saying "I should have..." and her voice was high pitched.Please if anyone can help that would be great.

Maybe she singed like this:
I should be crying, but I just can't let it show.
I should be hoping, but I can't stop thinking
