The American Idol Songwriter contest was also held this season. From ten of the most popular submissions, each of the final two contestants chose a song to perform, although neither of their selections was used as the "coronation song". The winning song, "The Time of My Life", was recorded by David Cook and released on May 22, 2008.
Try to answer this question if possible (otherwise reply "unanswerable"): What year did David Cook release the single, "The Time of My Life"?
2008
