Listen to these nostalgic tracks as you roam through a ruined Tokyo.
The two background tracks for the world map and battle sequences in the Vortex World can be replaced with world map and battle music from the Unclean Ones' Country Map in SHIN MEGAMI TENSEI IV. Music can be changed at anytime from the "Configuation" menu in-game. *This can accessed after reaching the Vortex World in the main story.
