Attila Music Mod for bi addon

basically i converted the mod attila total war music for rome remastered so that it could work on barbarian invasion for og rome,so you can play barbarian invasion or mods that have roman,barbarian,eastern,nomad and hun culture BUT nomad,hun and barbarian use the same songs for now at least i am gonna make another version with where the huns have unique music for them later,for now enjoy playing bi mods with a music more apropriate for the era.
