Sia "Elastic Heart" (ft. the Weeknd & Diplo)
Among the many high-profile contributors to the soundtrack for The Hunger Games: Catching Fire is Aussie pop singer Sia, who got the Weeknd and Diplo to contribute her song "Elastic Heart," which has now hit the web.

The track is an electronic pop tune that mixes beefy production values with simmering soul drama. Sia's singing is powerful and emphatic, while the Weeknd's Abel Tesfaye performance is characteristically nuanced and, at times, delicate.

The soundtrack for The Hunger Games: Catching Fire is out on November 19 through Republic.
