Editing Sound Test

''Sounds'' returns in ''Ultimate''. Like ''Brawl'' and ''Smash 4'' before it, the option is available from the start with hidden tracks that need to be unlocked. CDs are removed and replaced with the new method of buying tracks directly from the [[Shop]]. Songs are now organized by [[universe]]; all major universes except for {{uv|Duck Hunt}} and {{uv|Ice Climber}} have dedicated categories, with all other universes sharing the "other" category. There is also an "all" category that contains every song from every universe. The ability to play music while the screen is turned off returns from the Nintendo 3DS version. This feature again requires headphones, both inserted into the jack as well as wireless Bluetooth as of [[Nintendo Switch]] hardware version 13.0.0. The favorite section has been updated into the playlist section; like in the Wii U version, players can star music tracks, with the added option of making and storing multiple unique playlists at the same time. In ''Ultimate'', {{SSBU|Duck Hunt}}'s noises are present, but those of {{SSBU|Samus}} and {{SSBU|Mr. Game & Watch}} are still missing for unknown reasons. A peculiarity specific to ''Ultimate'' is that, in the Japanese version, songs from English games use the localized English title rather than the original Japanese one. For example, the source game of the English version of ''{{SSBUMusicLink|WarioWare|Ashley's Song}}'' is listed as ''WarioWare: Touched!'', rather than {{ja|さわる メイド イン ワリオ|Sawaru Meido in Wario}}. The same principle mostly does not apply in reverse in the English version of the game, with the exception of the source game of ''{{SSBUMusicLink|Fire Emblem|Lost in Thoughts All Alone (JP)}}'' being listed as ''Fire Emblem: if'' instead of ''Fire Emblem Fates''. However, for unknown reasons, both remixed versions of that same track are listed as originating in ''Fire Emblem: if'' in English as well.
