British newspaper The Sun has reported that one of the tracks on the proposed album is called Can't Keep That Dingo Down, believed to be a defiant message railing against his victims and accusers.
The 85-year-old was sentenced in July 2014 to five years and nine months' jail for indecent assaults on four girls - one as young as seven - between 1968 and 1986.
Under Britain's parole laws he could be released from jail in May next year.
The Sun quoted a source saying, "Making music is helping Rolf survive prison. But rather than keep his material to himself, he's telling those around him he has every intention of releasing it.
"The stuff has rockier influences than the music he's known for, because he wants to get across his anger at what he sees as injustice."
Also featured will be a track called A Bird In The Hand (Is Worth Two In The Bush).
Harris was criticised last year for a song he wrote called Woodworm Women, about his victims and compensation culture including the line, "Come and join the feeding frenzy girls".
At the time the lawyer acting for his victims, Liz Dux, called for him to have his chance for parole taken away.
"The point of parole is for people to show some sort of remorse and here is someone behaving as he was before, with disdain and an attitude that he can behave how he wants," she said.
