features a large selection of music originating from a variety of series from both Nintendo and third party companies that have representation in the game. Every stage features a total of 10 music tracks, and players can adjust the frequency of these songs via the My Music menu.
While each stage does feature 10 songs, not all are available from the start; four songs for each stage must be unlocked by collecting the CD items that spawn rarely during battles. Additionally as some stages must be unlocked, the songs that are classified as "default" for them can not be heard until the player has met the correct criteria to unlock the stage. Once a song is unlocked, the player can listen to it in the Sound Test, where it is grouped with others of its series in alphabetical order instead of by which stage it plays on as it is in the My Music menu and on this page.
