What music have you added to the game? Put in almost all of the music from More Songs and Music from Gettysburg which is great for fife and drum and band (I didn't do any of the singing tunes). I'm a fan of fife and drum so I also put some of the tracks from this in there:

Also an interesting page about Civil War music with a historical fife and drum guide from 1865:
