With mere weeks to go until the release of Fifty Shades Darker [1], our Winter is getting a whole lot steamier. And no, we're not just talking about the film's hot trailers [2] and handful of teaser pictures [3]. We're referring more to the full soundtrack [4], which is packed with high-profile names from Sia to John Legend [5]. Up until this week, we'd only really gotten a taste of Taylor Swift and Zayn Malik's collab [6], but now Halsey has added her song, "Not Afraid Anymore," to the mix. Check it out below.
