Sony Music has bumped the date of the “This is It” soundtrack one day. So all of you who were waiting for this project to be unveiled tomorrow? You can get it a day early. As you all know, the “This is It” movie, which contains footage from the rehearsals for what would have been a 50-date run at the O2 arena in London, opens wide on Wednesday.

This appears to be more of a collector’s item than anything else. I mean, let’s face it. Most people own Michael Jackson’s greatest hits already. I found out from GG that the unreleased stuff (a spoken word poem and a few demos) are available separately on iTunes. However, for those of us that are record collectors, I hear the set has a SWEET booklet and the packaging is really stellar. For someone like me (who already owns MJ’s greatest hits in 4 or 5 different configurations), this is a no-brainer. I’ll have my copy by the end of the day.

You can preview the demos on Michael Jackson’s website.
