Jay Z's music streaming service Tidal has reportedly fired its CFO

Tidal, the music streaming service owned by rapper Jay Z and a collection of other celebrities, has reportedly fired its CFO Chris Hart over a dispute about how the company handles user and streaming numbers, according to Swedish news site Breakit.

Hart has worked as CFO of Tidal since 2014, and he has been with the company since 2012. But Breakit's report says his departure came after an internal debate over internal metrics.

It was reported last week that sales of Kanye West's new album "The Life of Pablo" were left off the charts because Tidal didn't provide streaming data to Nielsen Music. It's currently unclear whether the argument that caused Hart's departure is linked to that incident.

Tidal has seen a string of high-profile departures from the company since it was acquired by Jay Z last year. The service has lost two CEOs, its chief investment officer, the US marketing manager, the senior vice president of label and artist relations, and now its CFO is reportedly gone too.

Tidal was not immediately available to comment.
