Stronger (What Doesn't Kill You)

"Stronger (What Doesn't Kill You)" is a song by the American singer Kelly Clarkson and the title song from her fifth studio album, Stronger (2011). Originally titled as "What Doesn't Kill You (Stronger)", the song served as the album's second single on January 17, 2012, through RCA Records. Written by Kelly Clarkson, Jörgen Elofsson, Ali Tamposi, and David Gamson, with additional writing and production by Greg Kurstin, "Stronger (What Doesn't Kill You)" is an uptempo song that draws from the genres of dance-pop, electropop and pop rock. Its lyrical content mainly explores themes of empowerment and recovery following a heartbreak, with the chorus inspired by a Friedrich Nietzsche quotation: "What does not kill me makes me stronger." The song was positively received by music critics, although some noted the cliché nature of the title's phrase.
