Following "4 More" and "One to Many," the latest video salvo from Samsung's Jay-Z marketing blitz finds the rapper/mogul ruminating on one of the key tracks off Magna Carta Holy Grail. Speaking to a supine Rick Rubin, Jay explains that his song "Heaven" toys with the idea of heaven or hell on earth. "Have you ever been to heaven?" he asks. "Heaven is in your daughter's laughter. Hell could be if your child is missing for three minutes." Check out the clip below, and remember to hit up the Google Play store to download the Magna Carta app, available for the Samsung Galaxy S4, SIII and Note II.
