The lawsuit was filed Tuesday. The defendant could not be reached for comment Thursday despite repeated attempts.

The estate is asking a judge to permanently ban Shadid from distributing Prince's works. It also is asking the judge to order Shadid to pay damages and attorney fees and costs.

The music icon's estate is accusing Phil Shadid of committing copyright infringement for profit.

Shadid is accused in the lawsuit of posting videos involving the album "Vanity 6" on TuneCore in violation of the estate's copyright. TuneCore is a do-it-yourself digital music distributor created to help independent artists get their songs heard.

TuneCore removed the "Vanity 6" videos at the estate's request but Shadid contested the action, according to the lawsuit. The estate told the judge TuneCore would have reposted the videos if it hadn't sued.

Prince died on April 21, 2016, at his home in Minnesota of an accidental drug overdose.

He was one of music's true superstars, beloved by his fans both for his skill in songwriting and for his electrifying performances on stage.
