She didn’t leave much behind. That’s the inescapable fact of Amy Winehouse’s posthumous collection, “Lioness: Hidden Treasures.” The album’s 12 songs are the leftovers from a singer and songwriter who was promising on her 2003 debut album, “Frank”; fully herself and even more promising on her 2006 album, “Back to Black”; and then a long, sad story until her death from alcohol poisoning this year. The transformation from the confident, sly, sweet-and-sour-voiced 18-year-old in 2002 to the scratchy, ravaged latter-day star is the album’s inevitable back story, even as the music stays chipper.
