Podcast uses for stingers and vamps:
Transitions: Signal a transition from one segment or topic to another. E.g., sound indicates that the hosts are moving on to a new segment or guest.
Breaks: A brief musical interlude or background music during breaks in the podcast or before/after ads. This can help to maintain energy and engagement between segments and prevent listeners from getting bored.
Emphasis: Emphasize an important point or punchline. For example, a dramatic chord might be played to highlight a surprising or emotional moment in the conversation.
