How to i get the sound i used to be heard by everyone in the server?

So, I've got this script and everything done and when i test it i can hear the music. But when i tested it in game with a player only i could hear the music playing.

local MOUSE_ICON = 'rbxasset://textures/GunCursor.png'
local RELOADING_ICON = 'rbxasset://textures/GunWaitCursor.png'
local g = Instance.new("Hint",workspace)
local Tool = script.Parent

local Mouse = nil

local function UpdateIcon()
	if Mouse then
		Mouse.Icon = Tool.Enabled and MOUSE_ICON or RELOADING_ICON
	end
end

local function OnEquipped(mouse)
	script.Alarm:Play()
	g.Text ="THE FINAL BOSS HAS BEEN SPAWNED!!!"
	wait(5)
	g:Remove()
	script.Alarm:Stop()
	script.Final:Play()
	Mouse = mouse
	UpdateIcon()
end

local function OnChanged(property)
	if property == 'Enabled' then
		UpdateIcon()
	end
end

Tool.Equipped:connect(OnEquipped)
Tool.Changed:connect(OnChanged)

This script is held as a localscript, i was thinking its because of that but it seems like i have no other way of making it work. i need it so that when the tool is acquired the g.Text shows and the music can be heard by everyone, i also have a problem with the g.Text only showing for me too.
