pop'n music 3 is one of the many titles in Konami's long-running rhythm game franchise, and the first of two "Append Discs" that require either pop'n music 2 or another Key Disc in the series in order to play. This particular release includes new music from the arcade version, and also includes many of the secret unlockable songs and modes from the previous releases available from the outset, in addition to new high-difficulty options such as Hi-Speed and Turbo settings in Survival mode.
