Country singer Brad Paisley and LL Cool J have been met with a storm of derision after releasing a duet described as "a strong contender for the worst song of all time".
Accidental Racist begins with Paisley, a rising country star, trying to apologise to a Starbucks employee for wearing a shirt emblazoned with a Confederate flag into his shop.
"To the man who waited on me/At the Starbucks down on main/I hope you understand/When I put on that T-shirt I only meant to say that I'm a Skynard fan," he says.
Lynyrd Skynyrd, the band name-checked, are a country group known for their pride in their southern roots.
The secessionist Confederate states fought to keep slavery in place in the US Civil War.
