Two new disputes are why people are searching. In early September 2026 a federal judge in Los Angeles threw out the broadest claim in the reggaeton “dembow” case, and on October 1, 2026 Rolling Stone reported a new suit claiming an Olivia Dean song copies Bill Withers’ “Just the Two of Us.” These are fights between songwriters, publishers and labels. They are not class actions: there is no settlement, no fund and no claim form for listeners.

How a Music Copyright Lawsuit Works
Every music copyright lawsuit has to prove two things. First, the plaintiff owns a valid copyright. Second, the defendant copied protected parts of that song. The Ninth Circuit spelled this out in the Led Zeppelin case in 2020.
Copying is rarely admitted, so it is usually shown indirectly: the defendant had access to the earlier song (it was a hit, it was sent to them, they played it) and the two songs are similar. Unlawful appropriation then requires substantial similarity in protected expression. In the Ninth Circuit that means passing two tests: an “extrinsic” one, where experts break the songs into elements, and an “intrinsic” one, where the jury judges the overall impression.
Two limits decide most cases. Fame does not lower the bar: the court rejected the “inverse ratio rule,” under which strong access meant less similarity was needed. And commonplace building blocks — a descending scale, a standard chord progression, a short repeating figure — belong to everyone.
Case Details
Most of these cases are tried on expert evidence. Each side hires a musicologist who transcribes both songs and compares them element by element: melody, rhythm, harmony, lyrics, structure. For melody, the comparison is about pitch sequence and the distance between consecutive notes — the intervals, counted in semitones — plus where those notes fall in the bar. Two melodies in different keys can still match note for note in their intervals, which is why experts compare shapes rather than letter names.
The experts then argue about what is original. In Williams v. Gaye (Blurred Lines) the court noted that the experts “disagreed sharply.” In Gray v. Hudson (Dark Horse) the trial centered on musical experts, and the appeals court held the shared figure was built from commonplace elements.
One technical point matters for older songs: for works under the 1909 Copyright Act, the protected work is the sheet music deposited with the Copyright Office, not the famous recording. In the Led Zeppelin case the deposit copy for “Taurus” was a single page.
Status: What Is in the News Now
Reggaeton “dembow” case (Los Angeles federal court). The production duo Steely & Clevie argued that their 1989 recording “Fish Market” underpins the dembow rhythm, and the case grew to nearly 2,000 songs and more than 150 artists. Judge André Birotte Jr. had let it proceed in July 2026, then reversed himself in early September 2026, calling the claimed arrangement “an abstract amalgamation of elements extracted from multiple independently existing works.” Narrower claims that specific songs directly sampled their recordings remain alive.
Olivia Dean, “I’ve Seen It” (Los Angeles federal court). Mattie Music Group, the publisher behind Bill Withers’ catalog, alleges the song copies a melody from the 1981 hit “Just the Two of Us.” The complaint names Capitol Records, Universal Music Group and Dean’s publishing companies, not Dean herself, and cites a musicologist who found “substantial similarities.” The defendants had not publicly responded as of Rolling Stone’s October 1, 2026 report; nothing has been decided.
Who Can Sue — and Who Cannot
Only the owner of the copyright (or an exclusive licensee) can bring a music copyright lawsuit: a songwriter, an estate, a publisher, or an investor that bought a share of the rights. In the Ed Sheeran “Thinking Out Loud” litigation, for example, one plaintiff was a company that owned part of a co-writer’s interest in “Let’s Get It On.”
Fans and listeners are not parties. Buying, streaming or playing a song involved in one of these cases does not give you a claim, and a verdict does not create a payout for the public. If you write music yourself and think your work was copied, the questions are the ones above: do you own a registered copyright, can you show access, and is what was taken original rather than commonplace.
What a Music Copyright Case Can Pay
Actual damages plus the infringer’s profits. The owner proves the infringer’s gross revenue; the infringer must prove its deductible expenses and what part of the profit came from other factors.
Statutory damages instead. $750 to $30,000 per work, raised to up to $150,000 per work for willful infringement, or lowered to $200 for an infringer who had no reason to know. The owner may make this election any time before final judgment.
Attorney’s fees. Under Section 505 a court may award costs and a reasonable attorney’s fee to the winner, but it is discretionary.
The real-world scale: the original December 2, 2015 Blurred Lines judgment awarded $3,188,527.50 in actual damages plus infringer’s profits and a 50% running royalty (the amounts were later amended; see our Blurred Lines page), and the Dark Horse jury awarded $2.8 million before that verdict was wiped out. Our copyright damages calculator walks through the statutory ranges.

Three Things to Watch For
Big music verdicts make headlines, and headlines attract people who want your money or your data:
“Claim your share of the song settlement”
Sites or emails suggesting fans can collect from Blurred Lines, the dembow case or the Olivia Dean suit are false. These are disputes between rights holders; there is no fund for listeners and no claim form.
Fake copyright notices over music in your videos
Messages claiming a song in your post infringes and demanding a payment or a login to “resolve” it are a common phishing pattern. Check the notice inside the platform itself, not through a link in an email or direct message.
“Guaranteed” infringement reports for songwriters
Paid services promising that a hit copied your song often skip the hard parts: proof of access and whether the shared element is original at all. The Dark Horse and Sheeran rulings show how often commonplace material loses.
Music Copyright Lawsuits — Questions People Actually Ask
What has to be proven in a music copyright lawsuit?
That the plaintiff owns a valid copyright and that the defendant copied protected parts of it. Copying is usually shown through access plus similarity, and the similarity has to be substantial and in original, protectable expression.
What are the most famous music copyright cases?
Among the famous music copyright cases: Blurred Lines (the Gaye family won, upheld in 2018), Stairway to Heaven (Led Zeppelin won, 2020), Dark Horse (Katy Perry won on appeal, 2022) and Thinking Out Loud (Ed Sheeran won; the Supreme Court declined review on June 16, 2025).
Can I get money from one of these lawsuits as a fan?
No. These are not class actions. Only the copyright owners and the defendants are parties, and any damages go to the winning rights holder. There is no claim form for listeners.
Why do musicologists matter so much?
Juries cannot read scores side by side on their own. Experts transcribe both songs, compare melody, rhythm and harmony, and argue about what is original. In the Blurred Lines appeal the court noted the experts disagreed sharply.
Can a chord progression or a rhythm be copyrighted?
Common ones generally cannot. In the Sheeran case the courts found the chord progression and harmonic rhythm too unoriginal, and in September 2026 the dembow claim lost its broadest theory because the arrangement was assembled from several separate works.
How much can a copyright owner recover?
Either actual damages plus the infringer’s profits, or statutory damages of $750 to $30,000 per work, up to $150,000 if willful. A court may also award attorney’s fees to the winner.
What is the Olivia Dean lawsuit about?
Mattie Music Group, publisher of Bill Withers’ catalog, alleges “I’ve Seen It” copies a melody from “Just the Two of Us.” It sued Capitol Records, Universal Music Group and Dean’s publishing companies in Los Angeles federal court. As of October 6, 2026 nothing has been decided.
Is the reggaeton dembow case over?
No. As of October 6, 2026 the broad claim over the dembow arrangement has been thrown out, but narrower claims that particular songs directly sampled Steely & Clevie recordings remain in the case.
Separate from this case: were you injured in the last 2 years?
Class-action payouts are fixed amounts through an administrator. A personal injury claim is a different case — and often worth far more. Free estimate, no obligation.
