## New Lawsuit Filed
Universal Music Group and Sony Music filed a lawsuit against Suno, adding 61,000 new songs to the legal battle.

> Suno’s wholesale theft … threatens the entire music ecosystem and the numerous people it employs.
## Suno's V6 Model
Suno released a new ai model v6 in partnership with major music companies including Warner Music Group.
## Legal Argument
Umg and Sony claim Suno's v6 model is trained on outputs from earlier models, not new data, making it illegal.

> v6 is not a fresh start. It is the fruit of the same poisoned tree.
## Suno's Defense
Suno says its v6 model uses licensed content, community interactions, and team learnings to train the model.

> v6 was trained on content licensed from our partners, interactions including creations and preference signals from our community.
## Copyright Concerns
Umg and Sony argue Suno's model harms the music industry by saturating the market with ai-generated music.

> Suno is saturating the market, directly competing with, cheapening, and drowning out real human songs.
## Fair Use Debate
Suno claims fair use allows it to train models on copyrighted music, but Umg and Sony say this argument no longer holds.

> Suno cannot credibly deny the existence of a market in which it is now a repeat, paying participant.
## Historical Context
Umg and Sony previously sued Suno in 2024, with Warner Music Group settling in November 2024.
## Key Claim
Umg and Sony say Suno's v6 model is not a fresh start but a continuation of unauthorized exploitation of copyrighted music.

> Suno’s development of v6 continued, rather than ended, its unauthorized exploitation of plaintiffs’ copyrighted recordings.
## Key takeaway

Suno's v6 model uses copyrighted music from earlier versions, not new data, violating copyright law.
