how to make a day and night ambience work, and repeat?

I have a script in my game that allows smooth day and night, I also figured I could add a day/night ambience. however, the script does work in game. But. only the day ambience plays and the night will not, and I wish to have this play every day and night.

I have a current placeholder until I figure out how to use this script.

do 
game.Workspace.Day:Play()
wait (600)
game.Workspace.Day:Pause()

game.Workspace.Night:Play()
wait (600)
game.Workspace.night:Pause()
end

Use a while true do loop. It runs forever, which you want in your case.

while true do 
	game.Workspace.Day:Play()
	wait (600)
	
	game.Workspace.Night:Play()
	wait (600)
end

Also, I'm assuming your audio you want to play is 600 seconds long. As long as the property Loop is not enabled, you do not have to stop it.
