Sia

The new Hunger Games Soundtrack just keeps getting hotter and hotter. Already containing a lineup of notable artists such as Lorde, The National, Santigold, Ellie Goulding, Phantogram, Imagine Dragons, and Coldplay, you can now add a hot new track to the list courtesy of Sia. And what's more, it features The Weeknd and was produced by Diplo. Clearly this is a powerhouse single."Elastic Heart" is as smooth as it gets.  Abel Tessfaye's brooding and silky falsetto vocals compliment the oh-so-talented songstress Sia to perfection, no doubt owing in part to master producer Diplo, who chops up the beats in a manner that can't help but creating an epic track.The movie hits theaters November 22, 2013.
