By far the best meta-rule I ever instituted at my table is that each week it's a different player's responsibility to find a thematically-related "end credits" song after the end of the session based off of what happened.
It's a really good way to kind of synopsize a session after the fact, but also if a player knows its their turn next week, they might make sure to include a particular scene or moment that session to fit the song they picked out!
