Gameplay consists of choosing a song to sing (one of 35 in the game); a digital avatar that basically lip syncs the lyrics and dances around the stage as you sing, making the game more entertaining to watch than regular karaoke (the differences between characters are purely aesthetic); and a level for your little person to dance around in.
Once the song begins, you are given the task of singing said tune as closely to the original as possible. Lyrics are represented by lines that scroll across the bottom of the screen. The closer the line is to the bottom, the lower the note. The game recognizes vowel sounds, and only vowel sounds, so it is easy to "cheat" the game by holding one note and adjusting the pitch accordingly.
The following are songs that can be sung in the game. Take note that the music in the game (with the exception of a few exclusive tracks in the Xbox version) are all rerecordings not done by the original artists.
