我试着加了背景音乐到music，txt修改如下，结果不好使。
song = {
name = "叶振棠-大侠霍元甲(万里长城永不倒).mp3"
chance = {
modifier = {
factor = 0
NOT = { tag = JAP }
}
modifier = {
factor = 2
tag = CHC }
}
}
song = {
name = "许嵩-半城烟沙.mp3"
chance = {
modifier = {
factor = 0
manpower_percentage = 2.0
}
modifier = {
factor = 2.0
NOT = { manpower_percentage = 0.5 }
}
}
}
song = {
name = "The Mass.mp3"
chance = {
modifier = {
factor = 0
war = no
}
modifier = {
factor = 2
war = yes
}
}
}
song = {
name = "神圣的战争.mp3"
chance = {
modifier = {
factor = 0
NOT = { faction = comintern }
}
modifier = {

faction = comintern
}
}
}
