Counting down the days until the second "Hunger Games" movie, "Catching Fire," hits theaters? This new gem from the star-studded soundtrack should tide fans over for at least a few days. Called "Elastic Heart," the track is out from Sia. The Diplo-produced track also features The Weeknd.

The soundtrack, which will make its full debut on Nov. 19, three days before the film's Nov. 22 release, also features songs from Christina Aguilera, Lorde, Coldplay, and Patti Smith, among others.
