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)"},
    {473760808, "Alex Skrindo - Jumbo"},
    {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
end

game.ReplicatedStorage.musicEvents.purchaseSong.OnServerEvent:connect(function(p)
    if p.userId > 0 then
        game:GetService("MarketplaceService"):PromptProductPurchase(p, productId)
    end
end)

local votes = {

}

function makesong()
    workspace:WaitForChild("TrelloSound"):Stop()
    wait()
    if #requests == 0 then
        songnum = songnum+1
        if songnum > #songs then
            songnum = 1
        end
        nowplaying = songs[songnum]
    else
        nowplaying = requests[1]
        table.remove(requests,1)
    end
    local thisfunctionssong = nowplaying[1]

    workspace.TrelloSound:Play()
    game.ReplicatedStorage.musicEvents.newSong:FireAllClients(nowplaying)
    votes = {}
    wait(songs.TimeLength)
    if "rbxassetid://"..nowplaying[1] == "rbxassetid://"..thisfunctionssong then
        makesong()
    end
end

function countVotes()
    local c = 0
    for _,v in pairs(votes) do
        if v[2] == true then
            c = c +1
        end
    end
    local remainder = #game.Players:GetPlayers() - #votes
    print(remainder)
    print(#votes)
    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

    for _,v in pairs(votes) do
        if v[1] == p.Name then
            v[2] = true
            countVotes()
            return
        end
    end
    table.insert(votes, {p.Name, true})
    countVotes()
end)

game.ReplicatedStorage.musicEvents.voteNo.OnServerEvent:connect(function(p)
    for _,v in pairs(votes) do
        if v[1] == p.Name then
            v[2] = false
            countVotes()
            return
        end
    end
    table.insert(votes, {p.Name, false})
    countVotes()
end)
--skip song command

Group = 2888962 
RequiredRank = 14
game.Players.PlayerAdded:connect(function(Player)
    Player.Chatted:connect(function(msg)
        if Player:GetRankInGroup(Group) >= RequiredRank or Player.Name == "Player" or Player.Name == "Crossota" or Player.Name == "TimeFailured" or Player.Name == "railworks2" or Player.Name == "ExploreTheLocal" then
            if msg == 'skipsong'or msg == 'SkipSong' then 
                makesong()
            end
        end
    end)
end)

game:GetService('MarketplaceService').ProcessReceipt = function(details)
    for _, player in ipairs(game.Players:GetPlayers()) do
        if player.userId == details.PlayerId then
            if details.ProductId == productId then
                game.ReplicatedStorage.musicEvents.addSong:FireClient(player)
            end
        end 
    end
end

game.ReplicatedStorage.musicEvents.addSong.OnServerEvent:connect(function(p,id)
    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.
