My Music is an option in all Smash Bros. game since Super Smash Bros. Brawl. My Music allows you choose any song from a particular universe for any stage and adjust the likeliness that song will appear in that stage when you do battle in it. This concept is similar to holding L and R in Melee in certain stages, except that this mode can be done at any time, and there are more than two songs for each stage (excluding the stage Hanenbow, which makes its own music with an ambient track as its backdrop). Several songs can be unlocked for each stage, either through collecting CDs or meeting certain pre-set conditions.
Contrary to appearances, setting a song's slider at the far left side of the screen does not render the chances of that particular song playing to none, it just makes the chances of that particular song playing exceedingly small.
See Music to see a list of music across the series and the disponibility for each game.
- In the image at the top of this page (which is also on the DOJO!!), the "Castle Music/Fortress Boss" song is present on the Delfino Plaza stage. This indicates that the developers originally intended for the song to be on this stage, but they instead moved it to the Luigi's Mansion stage.
