Ever since Ozzy became known to millions as the dumb rock-star dad in the reality TV series The Osbournes, it’s been hard to take the former prince of darkness seriously. With his 10th studio solo album, Ozzy is once again trying to regain his heavy-metal crown. But Scream, a collection of lackluster numbers like “Life Won’t Wait,” is a far cry from his best work with Black Sabbath. Only the anthemic “Let Me Hear You Scream,” with its arena-ready chorus, has any real staying power. Maybe it’s time for a family album.
