A federal judge has blocked a sound engineer from releasing a five-song EP of unpublished music by Prince after the late superstar’s estate objected — but one of the songs is still available online.

George Ian Boxill worked with Prince on five tracks in 2006, and made at least one recording — called Deliverance — available Wednesday for online sales. Prince’s estate and Paisley Park Enterprises sued to block it.

U.S. District Judge Wilhelmina Wright granted a temporary restraining order to stop the music’s release late Wednesday.

But independent label RMA says the song Deliverance was released before the judge’s ruling, so it doesn’t apply. The song was available online Thursday.

The estate’s lawsuit says Boxill signed a confidentiality agreement that the recordings would remain Prince’s property. Prince sings and plays guitar and keyboard on the tracks.
