Garth Brooks is pulling the plug on his self-owned digital music service, GhostTunes. He created it in 2014 to have control over how his music was distributed digitally. Then, last October, Brooks inked a deal with Amazon Music Unlimited, allowing his albums to be purchased and streamed through that platform. “Music Row” reports, GhostTunes users will have until March 3rd to transfer all of their music to Amazon Music Unlimited at no charge. Those users, however, will have to subscribe to the service in order to continue to access that music once it’s transferred.
