"Titanium" is a pop song which draws from the genres of house and urban-dance. The song's lyrics are about inner strength. Critics were positive towards the song and noted it as one of the standout tracks from Nothing but the Beat. Sia's vocals received comparisons to those of Fergie and the song was also musically compared to Coldplay's work. "Titanium" attained top 10 positions in several major music markets, including Australia, Austria, Canada, Denmark, Finland, France, Germany, Hungary, Ireland, Italy, The Netherlands, New Zealand, Norway, Philippines, Thailand, Spain, Sweden, Switzerland and the United States. In the United Kingdom, it peaked at number one, becoming Guetta's fifth number-one single on the chart and Sia's first.

The song's accompanying music video premiered on 20 December 2011 but does not feature appearances by Guetta or Sia, instead focusing on a young boy (played by actor Ryan Lee) with supernatural powers. On 12 August 2012, the music video was reused for a Spanish language version of the song.
