Not surprisingly, the hard-working "Purple Rain" legend had his hands in many projects prior to his death, including a possible documentary with Jay Z and Stevie Wonder, PEOPLE can reveal.
Prince was not only a friend of Jay Z's, he was also a fan of his company, Tidal. "He praised Jay Z a lot and what he's doing with Tidal," Kelley Carter, Senior Entertainment Writer for ESPN's The Undefeated tells PEOPLE. "He thought that was very fair to musicians and entertainers and he had a lot of really great things to say about Jay Z."
So much so that the pair had ideas about working on a film together.
"They recorded a lot of their meetings so there could possibly be a documentary at some point," Carter adds, pointing out that the most recent conversation took place close to seven months ago. "Stevie Wonder was a part of these conversations too and these things were being videotaped for a personal collection that maybe one day he would release."
Last summer, Prince pulled all his music from streaming services and put them on Jay Z's Tidal. He then dropped his surprise final album HITNRUN there in December.

Although a documentary has yet to be confirmed by Wonder or Jay Z, one thing that Prince definitely had in the works was his memoir.
In March, the music icon made the announcement that he was putting together a book with the working title The Beautiful Ones, according to Rolling Stone. At the Manhattan club Avenue, he had told the packed audience, "You all still read books, right? The good people at Random House have made me an offer that I can't refuse. We're starting right at the beginning from my first memory, and hopefully we can move all the way to the Super Bowl. We just started, we're going as quick as we can, working tirelessly."
The memoir was slated for a fall 2017 release.
As for music, Prince, who was known for writing a song a day, is thought to have a huge amount of never-before-heard material. The New York Times reported in 1996 that his vault in his Paisley Park home had "at least a thousand" unreleased songs.
There had also been many more plans to tour and the artist was in the midst of his Piano & a Microphone tour. One week ago, the singer performed at the Fox Theatre in Atlanta, where he gave his final, emotional performance of "Purple Rain." The April 14 performance was postponed from the previous week due to the singer's illness.

Before the show, the legendary musician apologized to fans for canceling his shows the week prior – not knowing that the performance would be his last. "Once again, I would like to apologize for the cancellation. I was a little under the weather," he said in exclusive video obtained by PEOPLE.
Prince announced his tour in November 2015, with the initial start date in Europe at Vienna on Nov. 21. However, the tour was postponed twice due to ticketing issues and the Paris attacks.
In February, Prince opened the tour was in Melbourne, Australia where he paid tribute to his former protégé Vanity just one day after her death, dedicating "Little Red Corvette" to the 57-year-old singer.
That same month, Prince announced his first North American Piano & a Microphone tour dates with two performances on Feb. 28 at Oakland's Paramount Theatre. Following his Oakland shows, he held a two-night run in Toronto in March.
