Music script doesn't work anymore since yesterday?

2 days ago this was working just fine but yesterday it stopped.It's a music script.

local currentSong = Instance.new("Model")
currentSong.Name = "CurrentSong"
currentSong.Parent = game:GetService("ReplicatedStorage")

function playSong(song)
    local c = currentSong:GetChildren()
    for i = 1, #c do
        if c[i]:IsA("Sound") then
            c[i]:Destroy()
        end
    end
    local newsong = song:clone()
    newsong.Parent = currentSong
    local hint = Instance.new("Hint")
    hint.Text = "Now playing: "..song.Name
    hint.Parent = game.Workspace
    game.Debris:AddItem(hint, 5.5)
    newsong.Playing = true
    if song:FindFirstChild("Length") then
        wait(song:FindFirstChild("Length").Value)
    else
        wait(120)
    end
end
