Ex-Bungie composer Marty O'Donnell has asked his fans to destroy and stop sharing music that he released without permission.

In a video posted to his YouTube channel, the composer said that his fans should get rid of the music that he released following his departure from the studio. This was a court-ordered measure, the result of a legal decision earlier this year that found that O'Donnell was in violation of a 2015 injunction that was meant to stop him from sharing or performing unreleased songs from Destiny.

"To whom it may concern, I do not have and have not had since at least April 2014, the legal authority to possess or distribute non-commercially available material related to Destiny or Music of the Spheres - including material I composed or created while working for Bungie," he said.

"This material is owned by Bungie. If you posted any of these assets on a website or other publicly available platform, you should remove the content immediately. If you have copies of these assets, you should refrain from sharing and destroy any copies of them. This request does not apply to any Destiny or Music of the Spheres material that you lawfully obtained from commercially available sources."
