Taylor Swift and Arcade Fire talked with Rolling Stones about the hunger games. You can see the entire interview here.
"The Civil Wars had a show that night in L.A.," Swift says. "So they raced right over to T Bone's house. There's so many things he could've done production-wise to make that song bigger sonically than it is, but I think that would have possibly been a mistake. For him to have left the song as a lullaby is brilliant."
