Why aren't the songs repeating?

So, I've been working on a script that repeats some songs (MSCA through MSCD) on loop unless the Loop value is equal to 0, but when I test the game it plays MSCA and then silence. Why won't it cycle through the other songs? I'm not really too good with this kind of stuff, sorry if the answer is stupidly basic. btw this is all activated when a light (L) is turned on with a proximity prompt.

L.ProximityPrompt.PromptButtonHoldEnded:Connect(function(Toucher)
	BRCK:Destroy()
	
	Clicked = true
	
	MSCA:Play()
	
	L.Material = Enum.Material.Neon
	L.ProximityPrompt:Destroy()
	workspace.Light.Bulb.SpotLight.Enabled = true
	workspace.Light.Bulb.SurfaceLight.Enabled = true
	LNG.Contrast = 0
	
	repeat
		MSCA.PlaybackSpeed = MSCA.PlaybackSpeed + 0.01
		wait(0.01)
	until MSCA.PlaybackSpeed >= 1
end)

while Loop == 1 do
	if Clicked == true then
		if MSCA.IsPlaying == false and MSCC.IsPlaying == false and MSCD.IsPlaying == false then
			FirstTimePlayed = true
			MSCB:Play()
		end
		wait(0.01)
		
		if MSCB.IsPlaying == false and MSCA.IsPlaying == false and MSCD.IsPlaying == false then
			MSCC:Play()
		end
		wait(0.01)
		
		if MSCC.IsPlaying == false and MSCB.IsPlaying == false and MSCD.IsPlaying == false then
			if FirstTimePlayed == false then
				MSCA:Play()
			end
		end
		wait(0.01)
		
		if MSCC.IsPlaying == false and MSCB.IsPlaying == false and MSCA.IsPlaying == false then
			MSCD:Play()
		end
		wait(0.01)
		
		if Loop == 0 then
			break
		end
		wait(0.01)
	end
end
