TheFocalPoint doesn't work

[Norfeder]

I want a custom music track only play for the one who do the action. I tried to use TheFocalPoint but my friends told me they can still hear the music even they're using different characters. TheFocalPoint doesn't seems to with in character.lua 

RemapSoundEvent( "dontstarve/characters/mycharacter/music", "sound/mycharacter/music" )

local function playmusic(inst)
    if inst:HasTag("shouldplaymusic") then
        TheFocalPoint.SoundEmitter:PlaySound("dontstarve/characters/mycharacter/music", "mymusic")
        inst:RemoveTag("shouldplaymusic")
    elseif inst:HasTag("shouldstopmusic") then
        TheFocalPoint.SoundEmitter:KillSound("mymusic")
    end
end

local common_postinit = function(inst) 
    inst:DoPeriodicTask(1, function() playmusic(inst) end)
end

 

Any help would be greatly appreciated!
