After Sia morphed into modern pop music’s resident songwriter, penning tunes for Rihanna, Celine Dion, Britney Spears, Katy Perry, Beyonce, Lea Michele, and Kylie Minogue — whew! — while contributing to the occasional movie soundtrack, the Aussie singer-songwriter is back in full solo artist mode.

Co-written with Jesse Shatkin and produced by Shatkin and Greg Kurstin (Lily Allen, Kelly Clarkson), “Chandelier” previews Sia’s sixth studio album, due this summer. The verses may be a close cousin to Rihanna’s “Diamonds,” but this time the shiny object that serves as song’s focus is connected to a darker place. For Sia, who has previously sung about drinking to get drunk, “Chandelier” is about willfully escaping from pain through alcohol without regard to the consequences. The aftermath of “just holding on for tonight” is hinted in the single’s cover art.

And yet, because “Chandelier” is imbued with that special Sia magic — a knack for melodic hooks and a nakedly honest, blown-vocal-cords performance — the track transcends the heaviness that such a theme might otherwise suggest. She may continue to fight the fame of being a solo artist, but on “Chandelier,” Sia’s coming out swinging.
