I have been using some old civil war game music for my WDS games.
I initially tried the music from Grant & Lee Civil War 2.
Then I tried the JTS Battleground Civil War music for a change.
I liked the music in both of these.
I do like the WDS music by the way ,just wanted more variety.
I searched a little and found this archive.
Other users might get some entertainment from the music.
I normally turn music off in game ,whilst having VLC player running on desktop.
Another option is to convert mp3s to wav and drop them into game Music folder.
Only listened to some of it so far.
The ambience tracks might be too loud ,but the music seems like it is of a average volume level.
The site I found is here-

If you look at download options ,under mp3 you can get 91 files ,takes a short time to download 703meg.
