PlaybackLoudness script not looping after the next song plays?

Hello, I have this script where it changes the fov based on PlaybackLoudness but it only works once and stops working after the next song plays. Ignore line 3 as thats for displaying the current song in a music player I have.

local randomTrack = availableMusic[math.random(1,#availableMusic)]

	currentTrack.Value = "..."

	wait(2)

	randomTrack:Play()
	
	local ScreenShakeSettings = {
		CameraMinFOV = 70,
		CameraMaxFOV = 90,
		CameraMaxVolume = 1200
	}


	game:GetService("RunService").RenderStepped:connect(function()
		local CurrentLoudness = randomTrack.PlaybackLoudness
		local FOV = ScreenShakeSettings.CameraMinFOV + (ScreenShakeSettings.CameraMaxFOV - ScreenShakeSettings.CameraMinFOV) * (CurrentLoudness / ScreenShakeSettings.CameraMaxVolume)
		if FOV > 0 and FOV < 130 then
			CurrentCamera.FieldOfView = FOV
		end
	end)

	currentTrack.Value = randomTrack.Name 

	randomTrack.Ended:Wait() 
	
end

It's because you did not update the randomTrack value inside the function. That's why when the song ends, the function detects nothing from the song, but another song is still playing. You could try updating the randomTrack value inside the function.
