It's spring, so we have a song about the impending winter because cover songs don't exist in a conventional timeline. And not just any winter, but one that completely fails to anticipate Olivia Rodrigo. Stick Season, originally by Noah Kahan, covered by Alex Melton. 

Outro music is Good 4 U by the aforementioned Olivia Rodrigo, who isn't heard anywhere else in the episode — just to be clear.
