idle thought #31

(I'm still confused as to how to feel when I realized, while growing up, from C-3PO's reactions that R2-D2 is essentially swearing like a sailor in every scene.  Suddenly the droid's got a lot more character.  I'm just not sure how I'm supposed to feel about that character now.)

Question

For my country-listening readers out there, what songs could have triggered Xander's PTSD from Last Man's Dead?  It's mostly only a concept right now, and it might never be in a fic, just backstory, but I'm curious and don't really know the genre.
