Why does this play for 5 seconds then play a new song?

This should select an id from the table and play it (other part in a local script), but instead the song plays for like ~5 seconds and then another song is played, and it keeps repeating itself.

It never waits for an actual song to finish before playing a new one.

work.SoundBrick.Sound.Ended:connect(function()
			if not debounce then
			debounce = true
			-- added to debug
			work.SoundBrick.Sound:Stop()
			
			local randomSong = songs[math.random(1, #songs)]
			print(randomSong)
			wait(0.5)
			remotes.Events.PlaySong:FireAllClients(randomSong) -- add in params
			wait(4)
			debounce = false
			end
		end)

Get the length of the song (TimeLengh property) and put a wait() after the song is told to be played. The song should play fully.

Why it plays for 4 seconds, or 5, as you say, is because your debounce is set to 4. Meaning, after 4 seconds your script will re-loop and play a new song. Try to pick songs that are full length, which is 2 minutes, converted to 120 seconds. So for your wait, put wait(120), and it should work properly. This should be your final code:

work.SoundBrick.Sound.Ended:connect(function()
            if not debounce then
            debounce = true
            -- added to debug
            work.SoundBrick.Sound:Stop()
 
            local randomSong = songs[math.random(1, #songs)]
            print(randomSong)
            wait(0.5)
            remotes.Events.PlaySong:FireAllClients(randomSong) -- add in params
            wait(119.5) -- i did 199.5 because you have a .5 above this wait so this would make it exactly 120 seconds, which is 2 minutes, a full length roblox audio
            debounce = false
            end
        end)
