It so happens that on Jan 2nd a previously unrealeased Michale Jackson song hit the web via YouTube. It is not the full song but a snippet that lasts for about a minute and a half.
There are many people who have uploaded the song on YouTube and it is now doing the rounds. It appears that the song is Lenny Kravits song 'Storm' redone with MJ. With now people debating which version is better and it seems the majority is with the version done with Michael Jackson.
