Ah, I see.. I'll move it back then.
You don't need the names for those soundeffects. If you put a sound in the music or ambience folder (say music01.ogg) it will be in that music slot.
Changing the sounds that come with the game is not a good idea, because then you need to create somekind of installer to change those sounds, and then another installer to undo those changes. I'd not want my sounds to be changed, honestly.
