 " My Hands " was selected as the official theme song for the trailer of Final Fantasy XIII . The video game was first released in Japan on 17 December 2009 , which uses a different theme song called " Kimi Ga Iru Kara " , written by Masashi Hamauzu and sung by Sayuri Sugawara . However , international versions produced by NTSC and PAL feature " My Hands " as the official theme song . Gabriel Zamora for Examiner.com wrote that despite sounding " loud " compared to Hamauzu 's song , " My Hands " suits the nature of the video game and " seems to fit well . " She continued to write that fans had hoped that " My Hands " would not replace " Kimi Ga Iru Kara " completely , instead wanting a new track called " Eternal Love " to be the official theme song . Although , she noted that the use of Lewis 's track for the entirety of the trailer seemed to make this an " unlikely " notion .
