Jay-Z has officially become Jay Z. The rapper has formally dropped the hyphen from his name, albeit so quietly that no one really noticed for a while. Mr. Z was first listed as Jay (no hyphen) Z in the liner notes for 2011’s Watch The Throne, and his name was recently changed on iTunes, but no one really pointed it out until Billboard this week. The publication says it got official confirmation of the punctuation switch straight from the rapper’s label, issuing notice to all the copyeditors out there. It’s not as big a nomenclatural story as Snoop Dogg changing his moniker to Snoop Lion, but it’s a bit of a shake-up all the same, maybe.
