Lucent Heart allows players to buy on Item Mall items to create their own songs. To listen to their song you need to download them and put on the appropriate folder:
SubaGames\Lucent Heart\data\music folder\dancemusic
Important: After you download the song and put on the appropriate folder, make sure the song file name is the same as displayed on this page. Sometimes WordPress will rename the file. If the file name is not the same as the one of the maestro, you WILL NOT listen anything even if the file is on the proper place!
