 The main theme of the game is "The Messenger" by Your Favorite Enemies. The tracks "Cosmos" and "Chaos - Last Battle 1" are also performed by Your Favorite Enemies. "The Messenger" is the main theme song of the game, with lyrics from both "Cosmos" and "Chaos - Last Battle 1." "Cosmos" features female vocals, while "Chaos" is dominated by male vocals. In YFE's documentary on the conception of the songs for Dissidia, lyricist and vocalist Alex Foster admitted that the lyrics have no direct connection to themes of the game; rather, he left it up to the listeners to interpret the lyrics based on their own thoughts and ideas.
