Earlier this week, Amy Winehouse's 'Back to Black' was eclipsed by Adele's '21' as the top-selling British album of the 21st century. But Amy isn't finished selling records yet: 'Lioness: Hidden Treasures,' a posthumously assembled collection of covers and unreleased original tracks, moved 140,000 copies in its first week, debuting at No. 1 on the British albums chart.

Winehouse's father Mitch broke the news via Twitter, telling followers, "Just been told. Amy at number 1. 140,000 sold = £140,000 to foundation in one day. Well done baby."

Curated by frequent Winehouse collaborators Salaam Remi and Mark Ronson, 'Lioness' includes a dozen performances selected from "thousands of hours" of vocal tracks she left behind after her July death, including 'Will You Still Love Me Tomorrow?,' 'The Girl from Ipanema,' 'A Song for You,' and 'Body and Soul,' a duet with Tony Bennett that previously surfaced on his recently released 'Duets II.'

At the moment, Winehouse's father seems reluctant to sign off on further posthumous releases, but he doesn't sound like he's second-guessing anything from 'Lioness.' As he put it to his Twitter followers, "My heart is sad but bursting with pride."
