Some pop songs are about cars: Little Deuce Coupe, Mercury Blues, Rocket 88

Or history: The Battle of New Orleans, The Night Chicago Died, Song of the South

Social protest: 99 Luftballoons, Keep On Rocking in the Free World, I’m Not Ready to Make Nice

Or ponies: A Horse with No Name, Wildfire, If I Had a Boat, Ride 'Em Cowboy

Strange Fruit isn’t about the South?

Warrant “Uncle Tom’s Cabin”
Vixen “Hard 16”
Europe “Cherokee”, “Ninja”, “Final Countdown”

Popular songs not about romance?

Here are two topics about as far from romance as you might imagine:

a) Cannibalism: “Timothy” by the Buoys, reached #17 on Billboard in 1971

b) Tooth Decay: “Savoy Truffle” by the Beatles, album reached #1 (not sure if it was ever released as a single), and “Ache” by No Doubt (but didn’t chart as far as I can tell).

OK, I’ll give you that one - most lynchings happened in the south. But in that era, most of the songs about the south were about how wonderful it was - songs like Basin Street Blues and Carolina Moon. I took Beware of Doug’s comment in that vein.
