Sia's "Chandelier" took 2014 by storm. As the lead single from her long-awaited album, 1000 Forms of Fear, the depression power ballad brought Sia--the woman behind many hits on the top 40--front and center as a solo artist. However, Sia is not a conventional pop star in that she refuses to tour and avoids the spotlight, not even showing her face at promotional performances. The perfect pairing of the song and video helped propel the tune to number eight on the Billboard Hot 100 and make 1000 Forms of Fear her first number one album in the US (after five other releases). Sia's talent and modesty make her a positive presence in pop music, and here's to hoping she has a great solo career ahead of her.
