If content services bite, it would be the latest prize from the late music legend to be fought over. Prince removed his songs from every streaming provider but Tidal back in 2015, but his catalog returned to other streaming services back in February. The estate reportedly isn't approaching Spotify to buy the concert film. The streaming service released its first documentary project last August, a four-part series on Metallica's early days. But Apple might be interested given that we learned last week that it plans to put a major focus on video content inside its streaming app. And that includes a number of exclusives including a Clive Davis documentary, Cash Money Records film and, of course, Carpool Karaoke... at some point.
