How can I loop audio for a certain time limit?

So far I've got this... But I want to make it so that after 10 minutes of one sound on repeat, a different audio plays? What am I doing wrong here? Do I need to add a loop in this script? If so how can I do that without breaking it?

local settings = require(script.Parent.Settings)

if settings.UseGlobalBackgroundMusic == false and settings.UseMusicZones == false then
	error("Cindering's BGM error: You have disabled both Global Background Music and Music Zones. You must change at least one of these settings to 'true'.")
	return
end

local name1 = "[1] Global Background Music"
local name2 = "[2] Background Music Zones"

local container = Instance.new("Folder")
container.Name = "CinderingBGM"

script.Parent.Settings.Parent = container

script.LocalBackgroundMusic.Parent = game.StarterPlayer.StarterPlayerScripts

local music = Instance.new("Folder")
local zones = Instance.new("Folder",music)
zones.Name = "MusicZones"
local global = Instance.new("Folder",music)
global.Name = "GlobalMusic"

if settings.UseMusicZones == true then
	local folder = script.Parent:FindFirstChild(name2) or game.ReplicatedStorage:FindFirstChild(name2) or workspace:FindFirstChild(name2) or game:FindFirstChild(name2,true) -- never know where someone might accidentally drag that folder...
	
	if folder then
		for _,model in pairs(folder:GetChildren()) do
			if (model:IsA("Model") and model:FindFirstChild("Music")) then
				model.Parent = zones
			end
		end
	else
		error("Cindering's BGM error: Your background music zones folder could not be found! You may have deleted/renamed the original folder. It should be named: "..name2)
		return
	end
end

if settings.UseGlobalBackgroundMusic == true then
	local folder = script.Parent:FindFirstChild(name1) or game.ReplicatedStorage:FindFirstChild(name1) or workspace:FindFirstChild(name1) or game:FindFirstChild(name1,true)
	
	if folder then
		for _,v in pairs(folder:GetChildren()) do
			if v:IsA("Sound") then
				v.Parent = global
			end
		end
	else
		error("Cindering's BGM error: Your global background music folder could not be found! You may have deleted/renamed the original folder. It should be named: "..name1)
		return
	end
end

if settings.UseGlobalBackgroundMusic == true and #global:GetChildren() == 0 then
	warn("Cindering's BGM warning: Your global background music folder is completely empty; no music will be played from there.")
end
if settings.UseMusicZones == true and #zones:GetChildren() == 0 then
	warn("Cindering's BGM warning: Your background music zones folder is completely empty; no music will be played from there.")
end

music.Name = "MusicFolder"
music.Parent = container

local count = 0
function recurse(instance)
	for _,v in pairs(instance:GetChildren()) do
		count = count + 1
		recurse(v)
	end
end
recurse(music)
local val = Instance.new("IntValue",container)
val.Name = "ObjectCount"
val.Value = count

container.Parent = game.ReplicatedStorage

script.Parent:Destroy()

You can add a for do loop where you want it to loop

for i = 1, 10 do --the ten is the amount of times you want something to repeat
	--stuff
end
