Congrats to Jay Z. Warner/Chappell Music, the publishing end of Warner Music Group, announced several deals with him to administer the copyrights of both his own songs and those on the music publishing roster of Roc Nation. The publishing company will immediately begin administering Jay-Z’s catalog starting from 2008 and by the end of 2013, they will also handle his early material. This will also include the administration for copyrights for Roc Nation’s songwriters. Part of the reason that Jay-Z chose Warner/Chappell was his connection to publishing executive Jon Platt, who left EMI Music Publishing for Warner last year. The duo first worked together in 1996, the year Jay-Z released his debut album, Reasonable Doubt.
