Go to /EB/DATA/ and look for descr_sound_music.txt. Then replace or add the old tracks back in. You can look up the name of the old tracks in the same text file for the vanilla game /Vanilla/Data. That song is called Divinitus (Campaign3-Divinitus.mp3). Of course you'd still need to pm Aemilius Paulus if you want candy. I have none.
