On the day we celebrate the signing of the Declaration of Independence, Jay-Z has given us Magna Carta Holy Grail. Or at least, he's given it to those Samsung users who have the right phone at the right time. So much for the spirit of democracy: If you don't have the app for that, you can wait until Tuesday.
For those craving a taste in the meantime, below please find "Holy Grail," the sort-of title cut that extensively features Justin Timberlake. So much so, in fact, that it might as well be a co-billing between JT and Jay-Z, who also teamed up on the former's "Suit & Tie" and will cavort together on their Legends of the Summer tour, coming to Hershey Park Stadium Aug. 4 and Citizens Bank Park on Aug. 13.
