Help me with sound, working on Studio but not Ingame?

I want to make a playist that plays music on my game. I want to load the next song before it plays so there is no delay (I use music that are more than 2 min long)

The first song plays, but it just does not trigger the ending event...

The thingis that this works in studio, but not ingame, It does not even do the "End" print ingame from the last lines of the script.

I want to know what's breaking my thing and how could I fix it.

This is the script:

local List = {
    [1] = "218607791";
    [2] = "218608165";
    [3] = "218609229";
}

local Music1 = Instance.new("Sound",game.Workspace)
Music1.Name = "Music1"
Music1.Volume = 0.1
local Music2 = Instance.new("Sound",game.Workspace)
Music2.Name = "Music2"
Music2.Volume = 0.1

local Current = Music2      -- I put this there so it changes to the Music1

local num = 1

function change()
    print("Changing")
    if Current == Music1 then
        Current = Music2
        Music2:Play()
        Music1.SoundId = "rbxassetid://"..List[num]
    elseif Current == Music2 then
        Current = Music1
        Music1:Play()
        Music2.SoundId = "rbxassetid://"..List[num]
    end

    if num == (#List) then num = 1 else num = num + 1 end
end

Music1.SoundId = "rbxassetid://"..List[1]
change()

Music1.Ended:connect(function()
    print("Ended")
    Music1:Stop()
    change()
end)

Music2.Ended:connect(function()
    print("Ended")
    Music2:Stop()
    change()
end)
