Some say it’s one of the “wildest music leaks in years.”

Whatever you want to call it, the fact is that about 50 gigabytes of otherwise unreleased Michael Jackson content has been stolen.

Kurrco, a Twitter handle that tracks music leaks, shared the news on Sunday (January 29), writing, “~50 GB of unreleased Michael Jackson content, including unreleased songs and demos, have leaked after a laptop & hard drive belonging to MJ’s engineer, Brad Sundberg, were stolen at a seminar this past Friday

“Wasn’t sure if I should post this here but this is like one of the wildest music leaks in years. Apparently, the guy who stole the laptop escaped by jumping out of a window,” the account shared.
