When McPhee walked into the room, completely unassuming, no one could have expected that she would go on to become one of Idol's most successful stars. Singing "God Bless The Child," McPhee showed off her incredible vocals and just enough of an indie-bluesy vibe to set her apart. She may not have won her season, but this audition was just the start of a steady career that's spanned television and Broadway as well as the music industry.
