What song from the 'Eclipse' Soundtrack do you think will be used while Rosalie is telling her story to Bella?

I have heard a small part of each song but I can not figure out what one might work, but Stephaine could suprise us, though...

I really like the songs 'My Love' por Sia and 'Heavy in your Arms' por Florence + the Machine. They could both work but they also fit with other parts in the movie, too.

What do you think???
