The first new Michael Jackson Song has been released since he died in what was classified as a homicide; and no, Palin was not responsible despite what some believe. This is not an official memorial, nor an unofficial memorial, just confirmation that there are some unreleased songs 'squirreled away' in a vault. The first of which, "This Is It", had been released to promote a new album which you can now reserve (see source of the clip).
