Why wont the music play when on server mode but plays in studio mode?

    local GUI = script.IntroGUI:clone()
    GUI.Parent = player:WaitForChild("PlayerGui")

    local Frame = GUI.Frame
    local Text = Frame.TextLabel

    pic.Visible = false
    music.SoundId = "http://www.roblox.com/asset/?id=193528674"
    music.Parent = game.Players.LocalPlayer
    repeat wait() until player.Character
    player.Character.Torso.Anchored = true
    Text.TextTransparency = 1
    pic.ImageTransparency = 1
    Text.Text = NameOfGame
    Text.Visible = true
    pic.Visible = true
    music:Play()
    Percent = 0
    wait(5)
    if ClassicLoading == true then
        ClassicLoad:TweenSize(UDim2.new(1, 0, 0, 200), "Out", "Quad", 5)
        while Percent < 100 do
            Percent = Percent + 1
            LoadText.Text = Percent .. "%"
            wait(5/100)
        end
        wait(1)
        while ClassicLoad.BackgroundTransparency < 1 do
            ClassicLoad.BackgroundTransparency = ClassicLoad.BackgroundTransparency + 0.05
            LoadText.TextTransparency = LoadText.TextTransparency + 0.05
            wait()
        end
        wait(1)
    end
    while Text.TextTransparency > 0 do
        Text.TextTransparency = Text.TextTransparency - .05
        pic.ImageTransparency = pic.ImageTransparency - .05
        wait(.05)

I looked it up and result is nothing I was a bit lazy that I had to look for plugins that made this. I modded it a little to support the picture and the sounds
