In Karaoke Revolution Presents: American Idol, gamers can work their way from tryouts to the finals based on the hit television show in an effort to earn a compliment from Simon Cowell himself. Beginning as just one in the crowd, gamers must select a character or add their image into the game with EyeToy camera, and then prove their vocal prowess in a series of competitions featuring 40 classic and contemporary songs. Stage presence is also judged and gamers can unlock additional clothing and accessories to create a crowd-pleasing couture costume. After each performance, judges offer verbal feedback and give players a score.
If successful, gamers will advance to the next level. However, a bad singing session will launch the digital version of Simon into a tirade full of uplifting and helpful comments including "That sort of singing should be illegal." While working through the game, players can unlock such content as clips from the show including performances by Clay Aiken. Gamers may sing alone or compete with friends in head-to-head or team games, and Karaoke Revolution Presents: American Idol also features classic Karaoke Revolution modes of play including "Duets," "KR Challenge," "Medley," and "Quickplay."
