More than 1,400 publishers have signed up to rights administration platform Music Reports in the two weeks since it partnered with Pandora.
Those 1,400 publishers collectively represent over 450,000 songs.
The internet radio platform made a deal with Music Reports at the beginning of June, with Music Reports set to manage the mechanical licensing and royalty administration for its upcoming interactive streaming service.
The deal was thought to avoid the kind of royalty lawsuits that have beset Spotify in the last year. Music Reports is a rival to SESAC's Harry Fox Agency.
Tim Westergren, founder and CEO, Pandora said: “Over 1,400 sign-ups in 14 days. That’s unprecedented in the publishing community - proof that opt-in licensing and full transparency is incredibly important to publishers. We’re proud to be setting a new standard for rights management in the digital era."
