A rhythm minigame that lets you input your own MP3 files or pick from premade music like the game’s OST. Gameplay could be similar to DDR where you use the arrow keys to hit a corresponding note. Milestones could be playable instruments (guitars, harmonica, maracas, tamborine, etc), an actual arcade machine that lets you play the game in your condo, a portable radio that lets you play a song of your choosing while in your condo or the plaza, or other music related items.
