Music industry mogul Scooter Braun said Friday his dispute with megastar Taylor Swift over her music catalogue has left his family receiving "death threats."

The 29-year-old pop artist began publicly sparring with Braun this summer over his company's purchase of her former label, Big Machine Label Group, which gave him a majority stake in the master recordings of her first six albums.

Last week, Swift - known for her calculating social media strategy - said on Tumblr that Big Machine heads were "exercising tyrannical control," claiming they were preventing her from performing at an upcoming awards gala and releasing a Netflix documentary including songs from her early catalogue.

In the post she pleaded with her fans and fellow artists to back her cause.

Braun had not publicly spoken out on the matter, but early Friday dropped a lengthy Instagram post saying Swift's appeal had resulted in "numerous death threats directed at my family."

"I assume this was not your intention but it is important that you understand that your words carry a tremendous amount of weight," Braun wrote.

"While disappointed that you have remained silent after being notified by your attorney 4 days ago of these ongoing threats, I'm still hopeful that we can fix this."
