I already mentioned "Love Story" by Taylor Swift. It refers directly to Romeo and Juliet.
Looking for the video, I found a link that broke down the lyrics to Billy Joel's "We Didn't Start the Fire."
The above could be obvious (depending on your generation). So I thought a little more about Billy Joel. I'm from Pennsylvania, and this happened before my time...but it is applicable. "Allentown" is based on the collapse of the steel industry. Bethlehem Steel was a big name in the industry. With the collapse of manufacturing currently, this could be a 'bridge' to past differences. It also addresses some other issues if you listen. I didn't see an embedded link for this one....so here's a link: Allentown Video. "Goodnight Siagon" also has powerful images and language regarding the Vietnam War.
Well, Billy Joel isn't exactly "Pop Culture" but there is a lot to be pulled from his work for educational purposes.
A little more current, but not by much (2007)...
If you can get past the idiosyncrasies, it is full of meaning. I'll let you figure them out. : )
