Ring the alarm! New Hova in the house! Jay Z is putting his mouth where his money is by launching the music video for "Glory" on — where else — his pet music-streaming service, Tidal. So of course we all have to go on and set up a free trial which we'll probably forget about. Whatever. It's Jay Z. It's worth it. Yeah, pretty much. Shot in 2012, the video shows Mr. Carter performing in a rehearsal with the orchestra at Carnegie Hall. You can just make out Alicia Keys and Nas joining the rapper as he plays proud papa. Those have got to be photos of Blue Ivy he's showing off on his phone, right? Speaking of Blue Ivy, Bey and Jay's pride and joy is the subject of "Glory," which was written in celebration of her birth. That alone is worth watching the video, though it is nice to see Jay cutting it up with a live orchestra at his disposal. Beyond that, you'll have to take our word for it. Only Tidal members can watch the video, so go ahead and think up of a new log-in password. Resistance is futile. We can, however, offer one quick sneak peek. More than that, and Hova will not be happy.
