The GUI will not display the current song. How can I get it to work?

Here is the music player:

while true do
    if not script.MusicOn.Value then
        local Music = game.ServerStorage.Songs:GetChildren()
        local RandomMusic = Music[math.random(1, #Music)]:Clone()
        RandomMusic.Parent = workspace.CurrentSong
        RandomMusic:Play()
        script.MusicOn.Value = true
        print(RandomMusic.Name)
        local musName = Instance.new("StringValue", workspace.CurrentSong)
        musName.Value = (RandomMusic.Name)
        RandomMusic.Ended:connect(function()
            RandomMusic:Destroy()
            wait(.1)
            script.MusicOn.Value = false
            return
        end)
    end
wait(.1)
end

Here is the GUI updater:

while true do
    local Music = game.ServerStorage.Songs:GetChildren() 
    local GUItext = game.Players.LocalPlayer.PlayerGui.MusGui.song_name.Text
    GUItext = workspace.CurrentSong.Value.Value
    wait(1)
end
