In terms of potentially unnecessary music celeb news, Jay-Z's buzz in the last week stands out as fairly interesting. Jigga and Beyonce recently took a trip to Cuba, which would be illegal for most American citizens. While the trip was being investigated by the US Government, apparently the little jet-set adventure checked out legally. Additionally, after many years of hustlin to get the New Jersey Nets moved to Brooklyn, apparently Jay-Z sold his share of the Nets for future endeavors into the sports world. This all might be somewhat irrelevant, but true to Jay-Z fashion, he addressed the haters in these situations via a brand new track called "Open Letter". Check it out below.
