Place it as the final element after your last line or reveal, with nothing scheduled after it in the timeline. For a TV parody cut, run the Law and Order Dun Dun Sound Button just before it, then let this credits theme close the sequence alone.
About this sound
This is a 16-second instrumental end credits theme, built as a moody electronic closing piece with no voices. It leaves a tense, nostalgic feeling, like staying seated after a finale instead of moving on. It comes from the end credits of the fifth season of Stranger Things.
