Some of the biggest record labels are grouping together to take down a fitness app that they believe is infringing on the copyright of the artists they manage. The array of artists includes Beyoncé, Bieber, Derulo, and more.

Fit Radio is a fitness app that encourages third-party DJs to upload popular songs to playlists on the app, which they then distribute to users for $3.99 a month or $79.99 for life. Sony, Warner Bros., Capitol Records and other major management companies sued the App for copyright infringement, claiming the app is damaging artists and companies that rely on royalties and licenses. They have branded the infringement to be on a “massive scale”.

“Defendants tout their service as the ‘#1 Workout Music App,’ and boast that they have millions of users,” writes attorney James Lamberth in a complaint filed Thursday in Georgia federal court. “Fit Radio has achieved this success because it infringes and facilitates the infringement of Plaintiffs’ copyrighted sound recordings on a massive scale.”

The labels are suing Fit Radio for direct, vicarious and contributory copyright infringement, as well as for inducing its DJs to commit copyright infringement. They are seeking an injunction to bar the service and statutory damages of up to $150,000 per infringed work.

Fit Radio has not yet commented on the complaint.
