Maybell plays music from the 1950s to the 1980s. None of the music used for this station was made in 1992, which is the setting of GTA San Andreas. The station broadcasts from somewhere in the desert, possibly from the radio tower by The Big Ear. Mary-Beth Maybell will sometimes play a harmonica in her pants.
Mary-Beth says after the song "Louisiana Woman, Mississippi Man" that she had 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."
After CJ begins to start missions with Catalina, Mary-Beth mentions about a rumor she heard about a young couple stealing across the state. It could be reference to CJ and Catalina stealing from stores across Red County.
Besides weather reports, Mary-Beth will comment on storyline events.
There is a real world radio station called "K-LOVE", which was founded in 1982. The name might have been inspired by it, but it's unknown.
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.
