NEW YORK (AP) — Amy Winehouse had written all the songs that were to appear on her third album. She even picked out song titles.

But music producer Salaam Remi said the soul singer, who died over the summer, was not rushing to release that new material, instead planning to drop a jazz album first with a “supergroup” including Questlove of the Roots.

“She had written down everything she wanted to do,” Remi said Tuesday.

Only two of the tracks Winehouse wrote were recorded and appear on her compilation album, “Lioness: Hidden Treasures,” out Dec. 5 in the United Kingdom, and a day later in America.

Winehouse died from accidental alcohol poisoning at age 27. Her body was found at her London home July 23.

Remi, who worked on the singer’s two albums, “Frank” and “Back to Black,” produced most of the upcoming CD, saying Winehouse was a perfectionist when it came to composing music.

“She was taking her time with it, and at the end of the day all of her songs are somewhat autobiographical, so she had to live through something, then get out of it and then look back at it to be able to write about it,” he said.
