Ozzy Osbourne has confirmed that Black Sabbath have written 15 new songs, NME reports. Speaking to the magazine, the frontman revealed the band has been working hard since reuniting last year, though he's not sure if all the new songs will appear on an upcoming album. Osbourne also dropped a hint on a possible title, saying, "Next year, 2013, is a good clue of what we'll call the album."
Black Sabbath will close the U.K.'s Download Festival on June 10th, a rare date featuring Osbourne, Geezer Butler and guitarist Tony Iommi, who is being treated for lymphoma. Original drummer Bill Ward has withdrawn from the reunion shows, citing contractual disagreements. The full video interview with Black Sabbath is available here.
