# After Judge Hellerstein denies leave to amend to add 30,000 songs to case, Sony Music turns around and files a 2d lawsuit v. Udio alleging 30,000 songs infringed > Source: > Published: 2026-07-20 20:23:01+00:00 **Sony Music Entertainment just sued Uncharted Labs d/b/a Udio in a second copyright lawsuit to allege Udio infringed 30,000+ additional songs. ** The second lawsuit comes less than a month after Judge Hellerstein denied Sony leave to amend the complaint to add those 30,000+ additional songs. See his Order below: This strategy is similar to the one the music publishers Concord Music used against Anthropic: the plaintiffs filed a second lawsuit after being denied leave to amend the complaint in the first lawsuit. Now, both *Concord Music I *and *Concord Music II* are before Judge Eumi Lee, who denied the motion for leave. If the past is prologue, we should expect a similar development here. **Excerpt:** **DOWNLOAD THE COMPLAINT:**
