studio album, We Are Born. The release peaked at No. 2 on the ARIA Albums Chart and was certified gold by the Australian Recording Industry Association. The release of the album was preceded by three singles: the lead single, "You've Changed", was released in December 2009 and charted at No. 31 in Australia. The follow-up single, "Clap Your Hands", peaked at No. 17 in Australia, No. 10 in the Netherlands and No. 27 in Switzerland. At the ARIA Music Awards of 2010, We Are Born earned Sia two categories won: Best Independent Release and Best Pop Release. Meanwhile, at the 2011 APRA Music Awards, Sia received a nomination for Song of the Year for "Clap Your Hands". To promote We Are Born, Sia gave the We Meaning You Tour, which visited North America and Europe in April–May 2010. She followed this with the We Are Born Tour, which visited Australia in February 2011 and North America in July–August 2011. 2010–2013: Songwriting career and mainstream recognition Following the success of We Are Born, Sia became uncomfortable with her growing fame.

She soon penned "Titanium" for American singer Alicia Keys, but it was later sent to David Guetta, who included Sia's original demo vocals on the song and released it as a single in 2011. "Titanium" peaked within the top ten of record charts in the United States, Australia and numerous European regions. However, Sia recalled: "I never even knew it was gonna happen, and I was really upset. Because I had just retired, I was trying to be a pop songwriter, not an artist." From 2011 to 2013, Sia also co-wrote songs for many recording artists, including Beyoncé, Kylie Minogue, Flo Rida and Rihanna. Her collaboration with Flo Rida, "Wild Ones", peaked at
