while true do script.Parent.Text = (game.workspace.Turntable.Selector.Disp.Frame.Playing.Text) end=
local turntableText = game.Workspace.TurnTable.Selector.Disp.Frame.Playing turntableText.Changed:connect(function() script.Parent.Text = turntableText.Text end)
Also while true do loops aren't very good always use while wait(0.5) do -- or any amount of time you want to wait
while true do script.Parent.Text.Changed:connect(function () script.Parent.Text = (game.workspace.Turntable.Selector.Disp.Frame.Playing.Text) end
