So there's a new song by The Lumineers called "Life in the City" (2019). It has the chorus:
This might seem familiar, because it's almost identical to the chorus of their song "Sleep on the Floor" (2016).
If the sun don't shine on me today
And if the subways flood and bridges break
Will you just lay down and dig your grave
Or will you rail against the dying day
This seems to me like an obvious sign that the songs are to be taken as related. But maybe they're just out of ideas. Like, is Weezer's "Look the Other Way" (2005) supposed to be connected to "Death and Destruction" (2002), or did Rivers just really like the line? There are some songs that are obviously connected, like Neil Young's "My My Hey Hey (Out of the Blue)" and his "Hey Hey My My (Into the Black)," but I don't see the obvious connection in The Lumineers' case. It's more like a "Saturday Night Live" skit that they bring back by basically just doing all the same jokes as the original skit (I'm looking at you, Ms. Rafferty).
