Samsung has purchased 1 million copies of Jay-Z’s coming album, entitled “Magna Carta Holy Grail,” slated for release July 4, and plans to give them to Samsung Galaxy smartphone users for free – 72 hours ahead of the release. The users are to receive the music through an app they’ll receive later this month. (Recipients won’t be able to share it until the official release date.)

Samsung paid $5 apiece for the albums, according to a person familiar with the matter. It wasn’t immediately clear if Nielsen SoundScan will count Samsung’s purchases in its sales tallies.

For Jay-Z, the deal is a precious advertising opportunity and gives him $5 million in sales before the album is even released. The agreement signals the increasing importance of corporate sponsors to the music industry, which has seen sales tank over the past decade.
