American Idol Contestants' Greatest Hits

David Cook, "Time of My Life"

For a few seasons of American Idol, ordinary people could submit songs to be considered as the first single for the Idol winner. David Cook's hit "Time of My Life" was one of those songs. And, well, it just proves that ordinary people can rock. This song is such a feel-good song, and David sounds oh so good singing it. (In our book, there's nothing wrong with a guy who is easy on the eyes and ears!) It was such an inspiring ballad, it became the anthem of the 2008 Summer Olympic Games.
