[Shayoo]

Hi ppl i know that there is an adanced jass tutorial way to add music to a lobby while being in multiplayer but i'd like to change this with trigger if possible, do i need to overwrite a music file with a path i don't know like:

Custom sounds :
TwostepsMusic.mp3 rename -> Sounds/BackgroundMusic/01.mp3
