Beatmania IIDX 16: EMPRESS + PREMIUM BEST is one of the many titles in Konami's IIDX rhythm game series, and the last release for the PlayStation 2. Including both a conversion of the arcade release, and a "Premium Best" disc, it features a whopping 180+ tracks from the arcade versions of IIDX 16 EMPRESS and IIDX 17 SIRIUS, original tracks produced for the home release, and a deep selection of returning tracks from throughout the entire series.

As usual for the beatmania series, the player is given seven piano keys and a turntable, and must play along with the notes that scroll down the screen to play the music. All of the game modes from the previous title have returned: Arcade, Expert, Class, Beginner's, Free, Training, and Gallery.
