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()
