Sia is burgeoning on becoming one of the biggest pop stars out there at the moment, and she does it all solely relying on her voice. She never performs in public and she doesn't appear in her music videos. She has a terrible phobia of performing live, but that doesn't stop her from ruling the charts.

Her first single 'Chandelier' off her upcoming album still gets played on the daily as I'm totally obsessed with it. It's arguably the best pop song of the year with its massive hook and booming beats. And it wouldn't be a Sia song without some incredibly dark lyrics that make you question whether she's ok or not.

The music video for the song was just released and it's a powerful visual. Maddie Ziegler, the famed star of Dance Moms, plays the featured role. The video consists of her in a Sia wig, doing a lyrical dance to the number that is visually haunting. As an avid Dance Moms fan, I don't think I've ever seen Maddie dance better. She brings the song to life. This is a huge moment for her, and her star power is only beginning to blossom.
