“I am black culture,” Beyoncé sings on “Black Culture,” which samples Michael Jackson’s “Don’t Stop ’Til You Get Enough.” The previously unreleased song, along with one called “Waiting,” is from a past recording session. 2009’s reigning diva, who was nominated for 10 Grammys this month, will perform at the 52nd Annual Grammy Awards on January 31, 2010.
