You know this song. You know you do!

OK, I heard this song on the radio and am hoping someone could help me figure it out. Kinda alternative rock with a female vocalist. The only lyrics I remember are from the chorus

"I say I hope, that you are worth, what I give up"

I may be off on them as they are not turning up answers. Any help would rock.
