Currently we're unable to implement new music in Zeus, it would be lovely if there was a possibility to increase the functionality of "Play Sound"/"Play Music" modules, so they could get the tracks defined in description.ext, under cfgSounds and cfgMusic.
edit:
Allowing tracks from mods would be sweet as well. Sounds added via mods sometimes work.
For example - AGM's cook off sound can be played via the sounds module, but the music that comes with AiATP cannot be played via music module.
