Originally released in 1992, The Chronic is arguably one of the greatest hip-hop albums ever to be released. However due to a long legal battle with Dr. Dre's former label Death Row Records, the doctor himself didn't win digital rights for the album until 2011.
"The album's absence could be explained, in part, over the rapper's legal battle over The Chronic with his former label Death Row Records. In 2011, Dre won back the digital rights of The Chronic after a judge ruled that the then-incarnation of Death Row could not sell the album digitally and granted Dre 100 percent proceeds of all Chronic online sales; Death Row retained the rights to The Chronic on all physical mediums."
Apple has a long history with getting what it wants when it comes to music. Just before the passing of the late Steve Jobs, the company was able to put The Beatles onto iTunes in 2010.
Apple Music is said to be launching Tuesday, June 30, at 8 A.M. PST after a quick update to iOS 8.4.
