I Still Looking For The Song Used In Biggest Losers And Night In Rodanthe Tv Ads. What Is It?

Is the song you're looking for "Taking Chances" by Celine Dion?  The lyrics are:

Don't know much about your life
Don't know much about your world but,
Don't want to be alone tonight
On this planet they call Earth
You don't know about my past, and
I don't have a future figured out.
And maybe this is going too fast,
And maybe it's not meant to last.

But what do you say to taking chances,
What do you say to jumping off the edge?
Never knowing if there's solid ground below
Or a hand to hold, or hell to pay,
What do you say,
What do you say?

I just want to start again,
And maybe you could show me how to try,
And maybe you could take me,
Somewhere underneath your skin?

What do you say to taking chances,
What do you say to jumping off the edge?
Never knowing if there's solid ground below
Or a hand to hold, or hell to pay,
What do you say,
What do you say?

And I had my heart beaten down
But I always came back for more, yeah.
There's nothing like love to pull you up,
When you're lying down on the floor there.
So talk to me, talk to me
Like lovers do.
Yeah walk with me, walk with me
Like lovers do,
Like lovers do.

What do you say to taking chances,
What do you say to jumping off the edge?
Never knowing if there's solid ground below
Or a hand to hold, or hell to pay,
What do you say,
What do you say?

Don't know much about your life
And I don't know much about your world.
