Song and artist in this commercial

I'll go ahead and turn in my man card with this question ...

What is the name of the song, and who is the artist, on the new "A diamond is forever" commercial?
It's the one with the couple driving at night in snow. He gives her a diamond necklace.
The lyrics say:

I think that possibly, maybe I've fallen for you/
Yes there's a chance that I've fallen quite hard over you/
I've seen the paths that your eyes want turn/
I want to come too

 

adtunes.com says that the song is by The Weepies and it is All that I want.

But I found the Weepies Web site and it doesn't sound the same.
It may be The World Spins Madly On, but I need to hear the commercial again

 

It very well might be The Weepies, but it's not either of those songs.
