Unreleased Winehouse songs about Blake

London - Songs Amy Winehouse recorded before her death were inspired by her divorce from Blake Fielder-Civil.

The 27-year-old singer - who was found dead at her London home on July 23 - had been working on a follow-up to her 2006 album Back to Black and the tracks dealt with the end of her relationship with Blake, who divorced her from prison in 2009, citing infidelity.

A spokesperson for her family 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 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."

According to the Mail on Sunday newspaper, the material will be released next year using vocals from Amy and her friends, with proceeds to be donated to the Amy Winehouse Foundation - the charity her father, Mitch Winehouse, wants to set up to help people overcome drink and drug addiction.

Meanwhile, Amy's breakthrough album, Back to Black - which was also inspired about her relationship with Blake, who she married in 2007 - has shot to number one in the UK album charts, while her debut album, Frank reached number five, and special package of both albums went to number 10.
