Ok, I found the music in the game annoying to say the least, I created my own three songs but tired of them too (German Lilly Marlene, Waffen SS march, I'll be seeing you, if anyone wants them let me know) so created three void songs. Because the cpu no longer has to access and play the songs while loading the turn, you will get a slight bump there.
Unzip the three music files into your game folder/data/z folder (if you don't have a Z folder in data then create one.
If you don't want to have to watch the intro video at start up go into CMBN data folder and rename the Intro video to Intro off.
