During certain aspects of the game, you will be given the opportunity to change the music that is played. These given aspects include the Battle Spot, The Battle Tree, and within Festival Plaza. Before each match within the Battle Spot and Battle Tree, you will be allowed to adjust the music you hear during the battle at the beginning of the match (some of these music themes are actually unlocked during the game). After reaching Level 40 within Festival Plaza, you will also be allowed to adjust its music.
