The songs on Amy Winehouse's unreleased third album were inspired by her former husband Blake Fielder-Civil.
There is speculation that the album, which is not titled, will now be released following the star's death last month at the age of 27.
A spokesperson for Winehouse's family told the Mail on Sunday that she had been working hard on the follow-up to 2006's 'Back To Black'.
He said: “Amy always had a notebook on her and would write down lyrics and ideas.
“People who have heard the new songs say that they are very, very good and that they are as autobiographical as ever.
“The period after 2006 was when Amy went through the most emotional upheaval, with Blake going to prison and then their divorce.”
As previously reported on Gigwise, 'Back To Black' has returned to the top of the album chart.
The album first reached number one back in 2006 and has now re-entered the UK top-ten along with Winehouse’s 2003 debut album ‘Frank’ at number five.
