Music Script Time.Length Not Working Correctly?

I am trying to get this music script playlist to work, after I changed wait(120) to wait(songs.TimeLength) it doesn't wanna play.

local productId = 9999999999
local songs = { --songid, name
	{290176752, "Yeah Yeah Yeahs - Heads Will Roll (JVH-C remix)"},
	{3314604270, "bbno$ & y2k - lalala"},
	{603146550, "Cartoon - On & On"},
	{674678896, "The Chainsmokers - Paris (Launchpad Remix)"},

	{678878009, "Bones - TakingOutTheTrash"},
	{2642540349, "Halogen - U Got That"},
	{2513053758, "Halsey - Without me"},
	{647317220, "Lukas Graham - 7 Years [Owen Remix]"},
}

local nowplaying = {}

local requests = {
	
}

function shuffleTable(t)
	math.randomseed(tick())
	assert(t, "shuffleTable() expected a table, got nil" )
	local iterations = #t
	local j
	for i = iterations, 2, -1 do
		j = math.random(i)
		t[i], t[j] = t[j], t[i]
	end
end

shuffleTable(songs)


local songnum = 0

function game.ReplicatedStorage.musicEvents.getSong.OnServerInvoke()
	return nowplaying

	else

	local percent = (c + (remainder/2))/#game.Players:GetPlayers()
	game.ReplicatedStorage.musicEvents.voteChange:FireAllClients(percent)
	if percent <= 0.2 then
		--skip song
		makesong()
	end
	return
end

game.ReplicatedStorage.musicEvents.voteYes.OnServerEvent:connect(function(p)
	for _,v in pairs(votes) do
		if v[1] == p.Name then
			v[2] = true
			countVotes()

	table.insert(votes, {p.Name, true})
	countVotes()

--skip song command

	for _, player in ipairs(game.Players:GetPlayers()) do

            if details.ProductId == productId then

	if tonumber(id) ~= nil and game:GetService("MarketplaceService"):GetProductInfo(tonumber(id)).AssetTypeId == 3 then
		table.insert(requests, {tonumber(id), game:GetService("MarketplaceService"):GetProductInfo(tonumber(id)).Name})
	end
end)

makesong()

And this is the error it gives me.
