Episodes two, three, and four all take place in a Diner located within the airport. The music gets deeper into the pop and rock direction. When Conor and Ash visit it, the bosses already took off because of the blizzard and left the young folk in charge, now playing their favorite music. When I wrote it, I sometimes imagined myself standing in the kitchen and watching the boys trying to find a way to get along.
2: I listened to this song when I was 16 myself. It’s not the music Ash and Conor would usually listen to, but it fits the mood of episode two perfectly for me: https://www.youtube.com/watch?v=UFKf08us2AI
3: This was another song that accompanied me through my youth and now found its way into this Story. https://www.youtube.com/watch?v=rdKfuwy6LUM
4: This is the last song on the Diner Playlist. The episode features two songs, one when Ash walks to the restroom and one shortly before they leave the Diner. In my opinion, this song would fit both occasions, as I heard it while writing the episode. But if this were a movie, it would be played in the latter part. https://www.youtube.com/watch?v=PuzvORd7wiM
Did you notice that Ash comments on some of the music played in the Diner? (With his taste in music in mind, of course.)
