After forgoing solo stardom to pen pop star hits—co-writing Rihanna's "Diamonds" and Beyonce's "Pretty Hurts"—Australian singer Sia returns with her first solo single in four years, "Chandelier."

Sia's raspy vocals tell the story of a party girl with an epiphany. "I'm the one 'for a good time call' / Phone's blowin' up, they're ringin' my doorbell... Gotta get out now, gotta run from this / Here comes the shame, here comes the shame / 1, 2, 3, 1, 2, 3 drink," she croons over a reggae-lite beat.

The chorus' booming percussion and marimbas back Sia's belting—only a handful of divas could pull off her half-scream vocals and still remain sonically pleasing. Lyrically, Sia is letting go of all inhibitions ("I'm gonna swing from the chandelier / I'm gonna live like tomorrow doesn't exist") while her vocals move from shouty wails to whistle notes.

The haunting tale details the Aussie's personal struggles with alcoholism and prescription drugs when she was still pushing her solo career. In a rare interview last year, she told Billboard, "I was really unhappy being an artist. I was always a drinker but I didn't know I was an alcoholic. Then I got seriously addicted to Vicodin and Oxycodone."

Now clean, Sia is expected to drop her sixth studio album—the follow-up to 2010's stomping pop-rock party We Are Born—in spring. Sadly, a clause in her contract stipulates she is not required to do promo or tour behind any records. But when pop music is this good, can we really complain? Great to have you back, Sia.
