How to make sound time position handling event?

Hello!
Recently, I wanted to make a little karaoke in my game.
It would work like this:
-The script notices that a certain piece of music is playing
-The script changes the text of the Label to the lyric of a specific passage that I have rewritten for it

Today I would like to focus on the bold part of the text.
I have a problem to make a handling event that will activate when a given piece of music is playing. How can I do that?

I have tried to do this with TimePosition before, but this function did not work for me or I used it
incorrectly.

:GetPropertyChangedSignal ??

GetPropertyChangedSignal won’t fire for a ‘Sound’ object’s ‘TimePosition’ property since it’s updated by the engine at a frequency greater than once per frame, you can however use a ‘RunService’ event loop to query the ‘Sound’ object’s ‘TimePosition’ property every frame.

local Game = game
local RunService = Game:GetService("RunService")
local Sound = nil --Reference to 'Sound' object.

local Connection

local function OnRenderStep()
	if Sound.TimePosition > Sound.TimeLength / 2 then --If audio track has reached its midpoint.
		Connection:Disconnect() --Disconnect event.
		--Code.
	end
end

local function OnSoundPlayed()
	if Connection and Connection.Connected then Connection:Disconnect() end --Prevents connection stacking.
	Connection = RunService.RenderStepped:Connect(OnRenderStep)
end

Sound.Played:Connect(OnSoundPlayed)
