Q: why does steve feel like everything's gonna be just fine but the mailman knows everything's gonna be just fine
A: it was necessary to change at least one word in the second jingle from the first. in the original draft, the second jingle was the same as the  first, but "fine" was changed to "alright." but during production i changed it to "know" and "just fine." the progression "feel like" to "know" is nice because it seems like we're gaining confidence. this is the exact same sort of lyrical strategy you might use in songrwiting, when varying the second chorus a little bit from the first
