Producer: Jacko Dazzles on Unreleased Ballad

We haven't heard the last of Michael Jackson's music. An unreleased ballad called "Don't Be Messing Around" ranks up there with his best stuff, says longtime Jackson producer Bruce Swedien. "Michael plays piano on it, and it's just beautiful," he says. "Oh my God, there's nothing like it." The song probably won't surface until Jackson's estate is settled.

It's not clear how many Jackson tracks are out there. “There might be one or two songs that didn't make it from each album,” said Swedien. “But they're not finished. There aren't vocals for everything.” Swedien, who worked with Jackson in his heyday, has a book out later this month called In the Studio with Michael Jackson. And though Jacko owed the producer $500,000, “it's nothing but good stuff.” (More entertainment stories.)
