Music can change the world because it can change people.
Sorry for the video quality, its just the video software, in game it doesn't effect it. If you want to make it work for Napoleonic wars you have to copy the music .txt file from the native module over to the Napoleonic wars module and (BEFORE YOU REPLACE THE NAPOLEONIC WARS MUSIC.TXT AND MUSIC FILE PUT COPIES OF IT SOMEWHERE ELSE)replace the Nap. wars music .txt file. Then you can put the EPIC MUSIC v.0.1 into the Nap. wars module and rename it to music. DONE!
If you want to know how to get it for Nap wars look in the description of this video.
