Unveiled with backing of some of music's top stars, the Tidal streaming service led by rap mogul Jay Z has gotten off to a rocky start. After a brief spike in interest following its relaunch on March 30, Tidal was on April 22, 2015 the 872nd most downloaded iPhone app in the United States, and the 51st among music apps. It has fared little better in most other countries. Sweden, Tidal's base, was the only country where it entered the top five list for downloaded apps, according to tracking service App Annie.

A federal judge on Friday refused to recuse himself from a $7 million (Dh25 million) copyright lawsuit against Jay Z over his Roc-A-Fella Records logo, after the plaintiff said the judge appeared to be biased toward the rap star and music entrepreneur.

US Magistrate Judge Ronald Ellis in Manhattan said there was no evidence that he showed “deep-seated favouritism or antagonism” in handling the lawsuit by Bronx clothing designer Dwayne Walker, or that his impartiality might reasonably be questioned.

In his July 2012 lawsuit Walker claimed that he created artwork in 1995 depicting a vinyl record that became the basis for Jay Z’s Roc-A-Fella logo, which includes a superimposed “R.” He is seeking damages for alleged copyright infringement from Jay Z, whose given name is Shawn Carter, and other defendants including Roc-A-Fella and its parent Universal Music Group Inc, a unit of France’s Vivendi SA.

In seeking Ellis’ recusal, Walker had accused the judge of issuing inconsistent rulings favouring Jay Z, and basing one order on a private call with defence lawyers.

“Walker mischaracterises both the facts surrounding these decisions and the supporting rationale provided by the court,” Ellis wrote.

Gregory Berry, a lawyer for Walker, did not immediately respond to requests for comment.
