Social media giant TikTok faces the prospect of another hit to its music catalogue following reports that the National Music Publishers’ Association (NMPA) is unlikely to renew its license with the platform when its deal expires on April 30.

The “NMPA’s TikTok license” is used by several independent publishers to enforce the legal use of their music on the platform.

In a letter to its members on Tuesday, the NMPA cautioned members that it “do[es] not anticipate” a renewal or extension after its slated expiration date, Billboard reports.

“Recently, the press has highlighted concerns around TikTok’s licensing practices, concerns that NMPA has heard directly from many of our members,” the organisation stated in its letter.

However, the NMPA urged publishers wishing to continue with its license to “engage directly with TikTok to negotiate a license beyond April 30.”

Publishers who want to allow the current deal to expire will have access to the NMPA’s legal team “to discuss enforcement options. It is important that all NMPA members understand that without a license in place, TikTok should not be using your musical works on its platform,” it added.

This news means that the platform would again be stripped of useable music for it users.

This comes a month after Universal Music Group pulled its entire catalogue from the video-based platform after hitting an impasse with the Music conglomerate in February.
