The track "New York City" was not listed in the included booklet guide for the first PS2 version, but was included in later versions.
After the song "Louisiana Woman, Mississippi Man", Mary-Beth claims she has never been east of the Mississippi River, but after another song, she starts talking about belt buckles, and she says she "bought a huge one in Florida the size of a hubcap."
There is a real world radio station called "K-LOVE", which was founded in 1982. K-Rose's name could possibly have been inspired by the station's name.
During the San Andreas Anniversary Weekend, it was possible to find a T-Shirt with the K-Rose logo in the random Special Crate drops in Grand Theft Auto Online as a wearable piece of clothing for the multiplayer character.
