Sia and David Guetta’s massive track “Titanium” soared as the fourth single from Guetta’s Nothing but the Beat. Visceral, tall lyrics accompanying daring vocals and addictive production, “Titanium” acts as an anthem against the critics and the bullies, equating vicious criticisms to bullets.

The song was originally written for Mary J. Blige among other artists (including Katy Perry and Alicia Keys). Blige recorded the song but instead of releasing her version, Guetta used Sia’s original demo without her permission (complying with Katy’s suggestion). It soon became a hit, and Sia acknowledges the choice as a major benefactor in her songwriting career.

Chartwise, it was extremely successful, becoming a top ten hit in 17 countries and moving 3.8 million units in the United States alone.
