Sony Music and UMG file new legal action seeking AI upload volume disclosure from DistroKid

What happened

Sony Music and Universal Music Group filed a new legal action against DistroKid seeking to compel disclosure of AI-generated upload volumes — data the labels describe as information only DistroKid possesses, directly tied to the market-effect question in AI-music litigation.

The claims

• The filing asserts DistroKid distributed nearly 12 million tracks to a single unnamed DSP between March and September 2026, more than all other distributors combined.
• It follows UMG's September 15, 2026 lawsuit (D. Del.) accusing DistroKid of flooding streaming platforms with 'mass AI-generated, SEO-optimized' tracks that dilute the royalty pool; Sony is not a party to that earlier suit.
• The new action brings Sony into the fight alongside UMG and targets the underlying AI-volume data itself.

Status

These are claims in a new filing, reported October 17, 2026, not court findings.
