*Jay-Z shown with a halo-like crown above his head. We've all heard him refer to himself as "HOV" or "Jay-Hova" which is a reference to Jehovah, the proper name of God in Abrahamic religions.
*Jay-Z premiered his video minutes after 2009 became 2010. I figured "On To The Next One" was a reference to moving on to the next year. In fact, 01/01/10 in Kabbalistic numerology equals 3 (0 + 1 + 0 + 1 + 1+ 0 = 3). There are groupings of 3 everywhere in the video, including the logo for his album "The Blueprint 3" which is 3 bars.
*Dark liquid being poured on a jeweled skull. The Knight Templars (ancestors of the Freemasons--hello, DaVinci Code?) made new members drink wine from a human skull as part of their initiation.
*Images of horns which references Baphomet-the horned idol reportedly worshiped by the Knight Templars and later used by the Church of Satan.
I don't know about you but I loved all this stuff in The DaVinci Code and I love it even more now that the coolest hip-hop business man is involved! Believe what you want but it definitely makes you watch your MTV Hits a little closer. There's not enough time in the world to analyze a Gaga video....
