These examples in the music section are all Zero Context Examples or at least need just a little bit more.
Bon Jovi's "Living on a Prayer" offers a sort-of optimism to folks in a similar situation (Bon Jovi also being from New Jersey). — What does New Jersey have to do with anything? What is this "similar situation"? Trope examples should not be referencing other trope examples on the page.
Jim Croce released "Workin' at the Car Wash Blues" in May 1974. — ZCE. The title of the song itself isn't enough to indicate the context of the song.
Stan Rogers’ “White Collar Holler” presents a semi-satirical song from the point of view of a computer coder. — Just barely avoiding ZCE, but really should have more context.
Perhaps the Trope Maker is "The Internationale", the famous anthem of Communists, Social Democrats, Socialists and Anarchists. — complete ZCE. Also, please clarify if it is or is not the Trope Maker.
"Working Man" by Rush qualifies. — Complete ZCE
"Roll On" by The Living End is specifically about the 1998 Australian Waterfront Dispute. — The wiki link to this specific event is pretty good, but more context for the page itself would really help.
