I'll start! for me, it's "Does anyone know/where the love of God goes/When the waves turn the minutes to hours" from The Wreck of the Edmund Fitzgerald, by Gordon Lightfoot.
It was always going to be a Seeming lyric and I could have picked a bunch that would have needed content warnings but I think this one comes out on top, from 'Talk About Bones':
Run run run on through the rain, don’t listen to the warnings
And all the skulkers saying someday you’ll come home
’Cause all they’ll find is your graffiti poems of cremation
That say, “You and me—let’s have a talk about bones”
In you, I see the glass towers coming down
In you, I see something that died in me fester and ignite
--"despair is a siren", for this we fought the battle of ages, subrosa, 2016.
Coming back for seconds might be greedy but any line from GSY!BE's Dead Flag Blues opening monologue
We're trapped in the belly of this horrible machine
And the machine is bleeding to death
Haunts me constantly.
