Quoted from JoshuahJacobs:
Zach pretty much nailed it. Further, the music, which I write, serves as indications to the listener of time changes, moments for reflection, or to accent the mood of the moment. For example, in this episode, the trapesqe beat with me spouting off phrases of frustration, highlight my love for the movie Planes, Trains, and Automobiles, as it's something Steve Martian says in the film. But also, to note the continued frustration I felt over many months, which is why the music goes on for 15 seconds or so longer than any other in the story. Thus, serves as a subtle indication of how difficult the task was getting as the months passed.
In the end, I understand that it may feel like 'filler' but there is a reason for placing such music in certain spots. Now when it comes to the music at the end, I write a new outro song for every episode and it's just my time to showcase some tunes. Once, I say "this is Josh Jacobs from the Pinball Network signing out" that is the end of the show. You may choose to listen to the music further if you like it or stop the player. Regardless, I want to thank you for listening and giving a new format a try.
This was something else. I loved it!
