How do I change a Player's GUI depending on a property?

I'm currently working on a GUI that shows the player what song is currently playing. I have gotten a Sound object with a script that keeps changing the song, and it works just fine. And I've also done a GUI in StarterGui that shows everything.

I have a Gui, Frame and TextLabel, inside the TextLabel is a script, that should change the player's GUI based on that property, this is how it looks like:

--\\ VARIABLES

local sound = game.Workspace.Misc.PlaySongs
local playerGui = game.Players.LocalPlayer:WaitForChild("PlayerGui")
local text = playerGui.CurrentSong.Frame.SongName

--// VARIABLES

--\\ CHANGER

if sound.SoundId == 3734646965 then
	text.Text = "Buttercup"
elseif sound.SoundId == 1560173003 then
	text.Text = "Oh Klahoma"
elseif sound.SoundId == 3524204087 then
	text.Text = "Dead Weight"
elseif sound.SoundId == 4664971308 then
	text.Text = "Life Could Be A Dream!"
elseif sound.SoundId == 3687583783 then
	text.Text = "Lolipop"
elseif sound.SoundId == 4509807932 then
	text.Text = "Chill Mix idrk lol"
end

But it doesn't change anything, I've tested it with a print("") as well, for some reason it does not see when the property is changed. Any help would be greatly appreciated! Thanks!

REMEMBER: the songs not only are composed with the id! they have an extension also "rbxassetid" look:

--\\ VARIABLES
	 
	local sound = game.Workspace.Misc.PlaySongs
	local text = script.Parent
	 
	--// VARIABLES
	 
	--\\ CHANGER
	 while true do
         wait(0.1)
	if sound.SoundId == "rbxassetid://3734646965" then --Convert the number value to string --value
	    text.Text = "Buttercup"
	elseif sound.SoundId == "rbxassetid://1560173003" then	    
           text.Text = "Oh Klahoma"
	elseif sound.SoundId == "rbxassetid://3524204087" then
	    text.Text = "Dead Weight"
	elseif sound.SoundId == "rbxassetid://4664971308" then
	    text.Text = "Life Could Be A Dream!"
	elseif sound.SoundId == "rbxassetid://3687583783" then
	    text.Text = "Lolipop"
	elseif sound.SoundId == "rbxassetid://4509807932" then
	    text.Text = "Chill Mix idrk lol"
	end
end

I also highly recommend to shorten the song list part,you will need it

And change the script to server script, not local
