Why music won't play?

Hello, I have problem with music gui. When player join to game it showing name of music which should playing, but i don't know why it don't work. Songs id's are fine.

Here is script from ServerScriptService > Random Music script which is main script:

_G["Last"] = {}


local Songs = {
	{179981960, "Avicii - Levels"},
	{190162862, "Avicii - The Nights"},
	{163884149, "Amnesia - 5 seconds of summer"},
	{174421816, "ERA - Ameno"},
	{152473326, "AJR - I'm Ready"},
	{163040671, "Queen - Crazy little thing called love"},
	{178768217, "TheLivingTombstone - Five nights at Freddy's"},
	{158630653, "Queen - Don't stop me now"},
	{151710009, "Frozen - Let it go"},
	{204128593, "Billy Joel - Piano Man!"}
}

repeat wait() until _G["Last"]

local Notice = script:WaitForChild("Notice")
local Debounce = false
local Song

if #game.Players:GetChildren() == 1 then wait(3) end

NextSong = function()
	if not Debounce then
		Debounce = true
		repeat wait() Song = Songs[math.random(1, #Songs)] until Song ~= nil and Song[1] ~= _G["Last"].Song -- This makes it so that it doesn't play the same song twice.
		_G["Last"].Song = Song[1]
		local Music = Instance.new("Sound",workspace)
		Music.Name = Song[2]
		Music.SoundId = "http://www.roblox.com/asset/?id="..Song[1]
		Music:Play()
		Notice.Value = ("Song Playing : "..Song[2])
		wait(Music.TimeLength)
		Music.Volume = 0
		repeat
			Music:Stop()
			wait()
		until Music.IsPlaying == false
		Music:remove()
		wait()
		NextSong()
		Debounce = false
	end
end
NextSong()

Here is script from Random Music GUI:

local Random_Music = workspace:FindFirstChild("Random Music") or game.ServerScriptService:FindFirstChild("Random Music")
local String = Random_Music:WaitForChild("Notice")
local Main = script.Parent
local Notice = script.Parent:WaitForChild("Notice")
local Shadow = Notice.Shadow

local debounce = false

local Anim = {}
	Anim.Duration = 0.4
	Anim.Type = "Sine"

local Update = function()
	if not debounce then
		debounce = true
		Main:TweenPosition(UDim2.new(0.3,0,Main.Position.Y.Scale,0), "Out", Anim.Type, Anim.Duration, true)
		Notice.Text = String.Value
		Shadow.Text = String.Value
		
		wait(4)
		
		Main:TweenPosition(UDim2.new(1.43,0,Main.Position.Y.Scale,0), "Out", Anim.Type, Anim.Duration, true)
		wait(Anim.Duration)
		Notice.Text = "" -- Not needed :P
		Shadow.Text = "" -- Also not needed, but why not? :P
		Main.Position = UDim2.new(-0.43,0,Main.Position.Y.Scale,0)
		debounce = false
	end
end

String.Changed:connect(Update)
