Lister said Garrido aspired to be a musician and gave him CDs containing about 20 songs three years ago because he knew people in the music business.
In one song, Garrido sings, "The way she walks, yeah, subtle, sexy. What can I do? I fall victim too. A little child, yeah, look what you do."
In another, he sings, "I will tell you about the only one. She's a dream, dream come true. With a note saying you're my baby blue."
Garrido told Lister the songs were written while serving time in federal prison in 1976 for the kidnapping and rape of another woman.
Lister, 57, allowed reporters hear portions of several songs on Friday at the Walnut Creek, Calif., office of his business attorney, Mark Mittelman.
"The language, the lyrics, they're suggestive and they're provocative in a lot of songs," Lister said.
Lister, who hired Garrido to print his business cards and invoices, said he plans to share the music with law enforcement if they want it but also hopes to raise money from it for abused women and children.
It wasn't clear on Saturday if investigators had contacted Lister, El Dorado County Sheriff's Lt. Bryan Golmitz said. But authorities would be interested in reviewing the CDs, he said.
"You can imagine the investigators have 18 years of material to review," Golmitz said. "They've got the initial portion done but there's going to be a lot of follow-up."
