Sound Test' is a part of Mario Sports Superstars that is always open, though some songs are locked until the condition to unlock them is done. It is accessed by going into "Collection" from the main menu then tapping the "Sound Test" button. This will bring up a list of songs which are mentioned below. Additionally, music doesn't play automatically, though there are songs that loop.
The game's music is composed by Motoi Sakuraba. Unlike Super Smash Bros. for Nintendo 3DS and Mario & Luigi: Paper Jam, music doesn't play when the system is in sleep mode.
