TikTok is muting more songs amid its tussle with Universal Music

is being forced to take down more music from its platform as a royalties spat with Universal Music Group (UMG) rumbles on. UMG recently it owns or distributes from TikTok including tracks from the likes of superstars Taylor Swift, Billie Eilish and The Weeknd. The standoff is now impacting songs published by UMG, with millions more tracks expected to be muted on TikTok by the end of this week.

The latest step in this saga affects works by artists who have partnered with songwriters who are under contract to Universal Music Publishing Group (UMPG), according to . Due to an issue called split copyrights, if a UMPG-contracted writer has contributed to a song in any way, that track may have to be removed from TikTok. So artists who have collaborated with the likes of Swift, Adele, Justin Bieber, Mariah Carey, Ice Spice, Elton John, Harry Styles and SZA may see their songs disappearing from TikTok and being muted on videos that currently use them. The move will prevent more artists from plugging their work on the most important platform for promoting music.

According to the , UMG removed around three million songs from TikTok after an agreement over its recording catalog expired. UMG’s deal with TikTok over its publishing catalog (which covers some four million songs) ends later this week, at which point all relevant tracks could vanish from the short-form video service.
