Sia Furler the "Chandelier" hitmaker has collaborated with electronic music producer Diplo for her new single titled "Waving Goodbye". The track is featured in Nicolas Winding Refn's new movie "The Neon Demon," reported Aceshowbiz. The mid-tempo ballad mixes Sia's powerful vocals and the thumping beat produced by Diplo. "One hand is holding your body/ The other is waving goodbye/ I love you but it's your turn to cry," she sings the chorus. "The Neon Demon" was screened earlier this year at the 2016 Cannes Film Festival.
