TO continue the music when the map bgm is the same as the battle bgm, go to scene_map and find

def call_battle
# Clear battle calling flag
$game_temp.battle_calling = false
# Clear menu calling flag
$game_temp.menu_calling = false
$game_temp.menu_beep = false
# Make encounter count
$game_player.make_encounter_count
# Memorize map BGM and stop BGM
$game_temp.map_bgm = $game_system.playing_bgm
$game_system.bgm_stop
# Play battle start SE
$game_system.se_play($data_system.battle_start_se)
# Play battle BGM
$game_system.bgm_play($game_system.battle_bgm)
# Straighten player position
$game_player.straighten
# Switch to battle screen
$scene = Scene_Battle.new
end

if $game_temp.map_bgm != $game_system.bgm_play($game_system.battle_bgm)
$game_system.bgm_stop
# Play battle start SE
$game_system.se_play($data_system.battle_start_se)
