Alicia Keys has been busy promoting her album Girl on Fire, but she turned the focus to another passion of hers—her new app The Journals of Mama Mae and LeeLee. The singer spoke to a crowd at the Apple Store in SoHo about the interactive app, which is now available for iPhone and iPad.

She was recently put in the hot seat during her visit to Baltimore’s 92Q Jams, and asked whether she thinks Nas or Jay-Z is a better rapper. “I will say Nas,” she told iiKane. “Obviously they’re both incredible lyrically, but Nas for me really goes to a place where he’s able to access concepts and storylines that most people wouldn’t be able to pull together.”

When asked whether Beyoncé or Mary J. Blige is a better singer, she gave the nod to B. “If you just heard her at a piano or a guitar, it’s really pretty spectacular how she sings,” said Alicia, who worked with Beyoncé on “Put It in a Love Song.”
