Help - Adding music to monster battle

I can’t seem to get MonsterMusic to works.

I tried using cronley “records/sounds/soundpak_musicambient/bosspak_act2_dariuscronley.dbr” as base for the music but even after build the mod using that, it doesn’t work, for example if i add the music to kyzogg. i also try same monstermusicradius.

changing music to “soundpak_ambient” works however, for example changing/adding other music to cave or cellar area.

any helpful hints are appreciated!

Ok silly me the hint was in the modding guide all along.
