Works on studio but not in-game, what's the problem?

The script is in a folder called "AudioController" and the music IDs are in another folder called "Songs"

local sound = Instance.new("Sound")
sound.Parent = game.Soundscape
sound.Name = "CoolAudio"

local number = 1
local songs = script.Parent.Songs:GetChildren()

local currentsong = 1
local nowplaying = 0

for i=1,#songs do
    songs[i].Name = tostring(number)
    number = number + 1
end

function cycle()
    local song = script.Parent.Songs:FindFirstChild(tostring(currentsong))
    if song == nil then
        currentsong = 1
        wait()
        cycle()
    else
        nowplaying = song.Value
        sound.SoundId = "rbxassetid://" .. tostring(song.Value)
        sound:Play()
        wait(sound.TimeLength)
        currentsong = currentsong + 1
        sound:Stop()
        cycle()
    end
end

cycle()
