I take it in the full game each faction will have their own theme song on the diplomacy screen, but all custom races do not.  Why not have it so a player can set their custom faction theme, from an mp3, For example I want to make a galactic empire type faction, and I want my theme to be something by Holst or Mozart. I'd even want a custom battle theme if possible to be something like Mars, Ride of the Valkyries or Hall of The Mountain King when I'm fighting them/ as them. Not sure how this would work online, i've seen it done before in some games.
