elasticity and music

It's the last day of the weekend (so enjoy it!), and what better way to end a fun couple days by a new release?

Aussie pop singer, Sia, has been cranking out albums since '97 with recent hits such as She Wolf, You've Changed, and Kill And Run.

Her latest is sure to become a hit. A track on the soundtrack of the second instalment of The Hunger Games, Catching Fire, here is Sia featuring The Weeknd and Diplo: Elastic Heart.
