EW.com said Jay-Z announced the release date for his latest project during a 3-minute Samsung cellphone commercial that aired during Game 5 of the NBA Finals Sunday night. The first 1 million Samsung Galaxy users to download a special mobile application will get the album 72 hours early, the entertainment news website said.
