"Ten months after Prince's death," reports the New York Times, "the last piece of the business puzzle for his music has finally been reached." Prince's estate has signed a deal with the Universal Music Group to release music not covered through Prince's contract with Warner Bros. — that means all of his albums released after 1995, and any previously unreleased material.

The Times notes, though, that Sunday's widely expected release of Prince's music across major streaming services will only include the Warner Bros. material: Musicology fans will have to wait. Most major services have all but officially confirmed the Sunday release, with Spotify taking out purple ads; Napster sent a press release on Thursday confirming that it would be carrying Prince's music as of Sunday.

Charles Koppelman and L. Londell McMillan, two industry pros who have been working with Prince's estate, talked with Billboard about their work to share and protect Prince's musical legacy.

"He really laid the groundwork for a lot of other artists who redefined the kind of deals they would make," says Koppelman. "So many more artists own most or all of their publishing and just do administrative deals; so many more artists have shorter terms on their recording deals and understand that they need to get ownership at some point."

The pair also confirm that there is not currently an active effort to determine what music from the Vault will be released; other deals need to be put in place first.

Ryan Adams remembers infamous heckler

In a New York Times essay, Ryan Adams remembers one of the most infamous heckling incidents in rock history: the time a concert attendee at Ryman Auditorium interrupted Adams's set with a shouted request for Bryan Adams’s hit "Summer of '69." Adams says that the incident was especially frustrating because he respects the other Adams as a songwriter, and sends him an e-mail every year on their shared birthday, Nov. 5. (Bryan is exactly 15 years older than Ryan.)

"I'm been around in this world causing drama, the real spice girl, hot girl power." Some heard that as a slight to her peers, but via Twitter, M.I.A. says she wasn't trying to dis any of those four.
