game.Workspace.Sound:play() script.Disabled = true script.Disabled = false
All sound instances have a property "Looped". It is set to false by default, meaning that the sound stops after it is played. Set it to true for the sound to loop.
game.Workspace.Sound.Looped = true
just do this :
while true do Workspace.Sound:play() end
it should repeat itself with "While true do"
