Sia Links With Pusha T for 'Unstoppable' Olympics Remix: Listen

Sia and Pusha T are getting into the 2016 Summer Olympics spirit, as the two have paired up for the "Unstoppable" remix. The original track (found on Sia's This is Acting album) was already anthemic, but it taken to worldly heights thanks to Ariel Rechtshaid.

The producer (who has worked with Carly Rae Jepsen, Haim and Charli XCX) adds strings and percussion from Afro-Brazilian marching band Olodum, making it a Rio de Janeiro-themed bop. Pusha's motivational bars ("Way more than physical, this is soul searching / The pain from the pressure to perform equals purpose") come through towards the end.
