Baz Luhrmann talks a little bit about what happened with plans for Prince to contribute to The Great Gatsby film. Apparently it was a version of Love... Thy Will Be Done. Although they'd "worked on it a lot," the piece was somehow "co-owned" and Prince "couldn't quite get it released." It's only a few sentences, but here's the link to the article:

The original contained a slowed-down sample of Fifty-Fifty Clown by Cocteau Twins. I don't think this was officially noted at the time of the song's release.

If he was re-recording the song, he could leave the sample out.

But... I think he used some of the melody too. If you listen to Fifty-Fifty Clown at the 2:20 mark, it sounds a lot like the bridge in LTWBD which starts, "And I see all of God's creation as one perfect complex."

Maybe the Cocteau Twins' publishers found out about Prince's use of the melody, and had to be paid retrospective royalties? They may have staked a claim for co-ownership of the the song in any form (re-recorded or not)
