Spotify removed hundreds of comedian’s albums and works from their streaming platform due to a dispute over royalties and copyright issues, the Wall Street Journal reported.

A global rights administration company, Spoken Giants, is working with a group of high-profile comedians to negotiate terms that would allow the comics to be paid when their work is paid on platforms like Spotify, SiriusXM, Pandora and YouTube, the Journal reported Saturday. Spotify removed work from performers such as Tiffany Haddish, Jim Gaffigan, Kevin Hart and John Mulaney.

“Spotify has paid significant amounts of money for the content in question, and would love to continue to do so,” according to a Spotify statement to CNBC. “However, given that Spoken Giants is disputing what rights various licensors have, it’s imperative that the labels that distribute this content, Spotify and Spoken Giants come together to resolve this issue to ensure this content remains available to fans around the globe.”
