Artist commentary:

ruby: (wiki editor)

This track is not in the game, however it has been added to simplify the references in the soundtrack. The "main theme" composition turned into the song we know as "Lifelight", and the "Main Theme", the latter of which does not actually exist. There is no Main Theme, outside of variations (E3 2018 version, Piano Solo). Battlefield, Menu, and Galeem / Dharkon are the most explicitely arrangements of this theme. Hence, those songs will be listed as referencing this song. There is no "concrete" main theme in SSBU, no definitive song to be considered the Main Theme, only songs referencing the common/shared composition. Lifelight is not the main theme, as "Main Theme Piano Solo" exists. As the E3 version is the most "complete" version we have, it will be treated as the common main theme for references.
