Another song from the Fifty Shades of Grey soundtrack [1] is here, and this time, it's from Sia, who's sort of our everything right now [2]. Instead of going the sexy route for the bondage-heavy film, Sia's song "Salted Wound" is romantic and slow and beyond gorgeous. I can't wait to see where this ends up in the film; it kind of sounds like an end sequence track, kind of moody, but beautiful.
