Donkey Konga was developed by the same team of people who made the Taiko: Drum Master series for the PlayStation 2. The songs include hits such as "Louie Louie", "We Will Rock You", "Shining Star", "Rock Lobster" and "Losing my Religion". There are songs from the Mario series, the The Legend of Zelda series and other Nintendo related music.
