During the course of her career, Sia Furler has been an in-demand guest vocalist, a quirky singer/songwriter, a hitmaker for the likes of Celine Dion and Beyoncé, and more popular than ever as an artist in her own right in the 2010s. On albums such as 2001's Healing Is Difficult and 2004's Colour the Small One -- which featured one of her definitive songs, "Breathe Me" -- Sia established herself as a singer and songwriter with a distinctively vulnerable voice. As time went on, she expanded her range to include the livelier fare of 2010's We Are Born and 2014's 1000 Forms of Fear, which included the Grammy-nominated single "Chandelier." During this time, she also became an in-demand pop songwriter, with Rihanna's 2013 single "Diamonds" among the biggest hits she wrote for others. Sia's success continued as the 2010s unfolded: 2016's "Cheap Thrills" became her first single to top the Billboard 100 chart.
