Internet hackers have managed to steal Michael Jackson's music from Sony's website.

The hacking occured in April 2011, at the same time Sony's Playstation Network was hacked, which revealed personal information for around 70 million users. However, as BBC reports, although the Michael Jackson hacking probably took place around the same time, it has only just been revealed.

In 2010 Sony Music payed $250 million to Jackson's estate for a seven-year deal to the rights of his remaining songs.
