List of Super Smash Bros. Ultimate in-game music

As with previous installments in the series, Super Smash Bros. Ultimate features a Sounds menu that allows the player to listen to the game's music and character voice clips.

Similarly to Super Smash Bros. for Nintendo 3DS, when playing in handheld mode, players can listen to music through headphones even while the Nintendo Switch's screen is turned off. Instead of marking songs as favorites, players can create their own playlists and add songs to them, including a built-in "Favorites" playlist. The playback functions return, allowing the player to listen to the entire soundtrack, play it in shuffle mode, or play a single song on repeat.

My Music works differently than it does in the previous two games in the series, in that music tracks are now sorted by series instead of by stage. For example, any music track in The Legend of Zelda series can be selected to play on any stage in that series.

A large selection of returning music from past Super Smash Bros. titles as well as new arrangements and remixes are available. There are a total of 1068 music tracks (including DLC) available in the game, making Super Smash Bros. Ultimate the game with the largest music selection in the series thus far.
