Personal music selection in mods

[Sfwartir]

I've recently installed the Mundus Magnus v.2 mod. However, my attempt to swap the RTW vanilla music with my own music failed miserably. I find this rather awkward, since I had no problem in adding new music pre-Mundus Magnus v.2: Create new folder in Data/Sounds folder, add selected music files to the new folder, add link to new folder in descr_sounds_music.txt. Finally, delete events.dat from Sounds folder.

Is there a more complicated process in adding new music to "provincial campaign" mods?
