How do I fix the "Play Sound" button in my admin panel? and the rest- too long

The issue is, is that, when I try to click the "Play Sound" button, (even on like... 1 hour long sounds) it just immediately changes the text to "Stop Sound" and another microsecond later it changes to "Play Sound" without playing the audio. The things I tried is inside the code block below.

local Module = require(game.StarterGui.eText)
local btn = script.Parent.Parent.BtnPlay
local input = script.Parent.Parent.Input
local sound = workspace.Sound
local playing = false

btn.MouseButton1Click:Connect(function()
	if playing == false then -- (<-- Which is this one) I tried to make it easier for the script to understand but didn't work, the previous one was
				 -- "if not playing then"
		sound.SoundId = "rbxassetid://" .. input.Text
		sound:Play()
		
		Module.ApplyText(btn, "Stop Sound")
		playing = true
		wait(sound.TimeLength) -- If I put it to 8 seconds, the sound will play for 8 seconds but
		-- I want it to wait for the sounds length but doesn't work
		sound:Stop()
		sound.SoundId = ""
		
		Module.ApplyText(btn, "Play Sound")
		Module.ClearText(input)
		playing = false
	elseif playing == true then
		sound:Stop()
		sound.SoundId = ""

		Module.ApplyText(btn, "Play Sound")
		Module.ClearText(input)
		playing = false
	end
end)

just put the sound inside the gui and the play and stop in different buttons like:

function Song()
	local ID = script.Parent.Parent.id.Text
	local sound = script.Parent.Parent.Parent.Music
	Sound.SoundId = 'rbxassetid://'.. ID
	Sound:Play()
end
script.Parent.MouseButton1Click:connect(Song)

and then

function Stop()
	script.Parent.Parent.Parent.Sound:Stop()
end
script.Parent.MouseButton1Click:connect(Stop)

-side note make sure the sounds in the gui and the buttons are in a frame id is a text box! :)
