In September 2024, a company most music fans have never heard of sued one of the most famous pop stars alive. Tempo Music Investments — an investment firm that buys and holds music-publishing catalogs — accused Miley Cyrus of building her 2023 juggernaut "Flowers" on the bones of Bruno Mars's 2013 ballad "When I Was Your Man." The case, Tempo Music Investments, LLC v. Miley Cyrus, No. 2:24-cv-07910, is pending in the U.S. District Court for the Central District of California before Judge Monica Ramirez Almadani, and it has become one of the highest-profile song-copyright fights since "Blurred Lines."
"Flowers" is not a minor target. It won the 2024 Grammy for Record of the Year and broke Spotify's record for the fastest song ever to reach one billion streams. Tempo's complaint reaches well past Cyrus herself: it names her co-writers, a long roster of publishers, and nearly every company that touched the song commercially — Sony Music Entertainment, Apple, Amazon, iHeartMedia, Live Nation, the major streaming platforms, and big-box retailers from Walmart to Target. When a single song is that successful, an infringement claim is never really about one artist. It is about the entire chain of businesses that monetized it — and about who, exactly, has the right to collect if a court ever says the song crossed a line.
What the lawsuit says
Tempo's theory is that "Flowers" copies multiple protected elements of "When I Was Your Man": the melodic pitch design and sequence in the verses, the connecting bass line, portions of the chorus, specific chord progressions, and certain lyrical and theatrical elements. The emotional symmetry is part of the story the complaint tells — Mars's narrator apologizes for what he failed to do for a partner ("I should have bought you flowers"), while Cyrus's narrator turns the same gestures inward ("I can buy myself flowers"). Tempo argues that the resemblance is not coincidence but copying, reproduced and commercially exploited without a license from a co-owner of the older song.
Here is the detail that makes this case worth a filmmaker's attention: Tempo is not Bruno Mars, and it is not his record label. It is a financial buyer that acquired a share of the "When I Was Your Man" copyright by purchasing the catalog of one of the song's co-writers, Philip Lawrence. In other words, the plaintiff owns a slice of the composition — enough, it argues, to bring suit; not the whole thing. That fractional posture runs underneath the entire dispute, and it is the kind of ownership question that decides who can enforce a copyright long before anyone argues about whether two melodies actually match.
Cyrus has denied wrongdoing and fought hard to end the case early. Her lawyers moved to dismiss, arguing — in the words that made the headlines — that "no one owns these words" and that the shared musical features are commonplace building blocks of pop songwriting, including what they described as a garden-variety "circle of fifths" chord progression that no one can monopolize. In March 2025 the court declined to throw the case out, letting it proceed into discovery; reporting at the time noted the judge's approach of sorting out liability before damages. Cyrus's team pressed the "unprotectable, commonplace elements" argument again as the case matured, and by early 2026 the two sides were openly fighting over whether the dispute should reach a jury at all, with the plaintiff's camp arguing that "where there's smoke, there's fire." Nothing on the merits has been decided. These are allegations and defenses, not findings, and being named as a defendant is not evidence of wrongdoing.
The hard part: what music copyright actually protects
Two legal ideas sit underneath this case, and the gap between them is where almost every music-copyright fight is won or lost.
The first is the idea/expression line, which in music is unusually unforgiving to plaintiffs. Copyright protects a specific, original expression — a particular melody, a particular arrangement of lyrics — but it does not protect the raw materials every songwriter draws from. A common chord progression, a scale, a standard song structure, a familiar sentiment: those belong to everyone. This is exactly the ground Cyrus is standing on when her lawyers call the shared elements "commonplace." The whole contest is about where ordinary craft ends and protectable expression begins, and courts have grown noticeably more skeptical of broad melodic claims since the "Blurred Lines" verdict rattled the industry. A case like this one tests, again, just how much of a pop song the law will fence off.
The second idea is co-ownership and the right to sue — less glamorous than melody-matching, but often decisive. A song with several co-writers is co-owned, and the rules governing what one co-owner (or someone who buys a co-owner's share) can do are technical and strict. Can an investment company that acquired one writer's fractional interest sue over the whole song? What must it prove about the chain of assignments that carried that interest from the songwriter's pen to a holding company's balance sheet? These are not footnotes. They are threshold questions that can end a case regardless of how similar two songs sound, because a plaintiff who cannot establish clean, enforceable ownership never gets to the part where a jury listens to the music.
Why it matters beyond one hit song
It is easy to file this under "billionaire pop star, faceless investment fund" and move on. That would be a mistake, because the machinery grinding away in this docket is the same machinery that governs a first-time filmmaker's rights — just at a different scale. The lessons here are not about Miley Cyrus. They are about ownership, documentation, and the unglamorous paperwork that decides who actually controls a creative work.
A few concrete takeaways, drawn straight from the pressure points in this case:
Co-ownership is a decision, not an accident. The moment more than one person contributes to a protected work — a co-written script, a jointly composed score, a collaboratively shot film — you have co-owners with independent, sometimes conflicting rights. Decide up front, in writing, who can license it, who can enforce it, and how money is split. The disputes that blow up years later almost always trace back to a collaboration no one papered at the time.
Chain of title is the asset. Notice who the plaintiff is: not the artist, but a company that bought a piece of a song. Catalogs, scripts, and film rights change hands constantly, and the value of what's bought or sold is only as good as the documented trail connecting the original creator to the current owner. If your assignments, options, and transfers aren't traceable, your rights are hard to enforce and hard to sell — and a collection account manager or distributor will demand to see that trail before a single dollar moves.
Register early, and register the specifics. Timely registration with the U.S. Copyright Office is what preserves statutory damages and attorneys' fees and gives you a dated, official record of exactly what you created. Just as important, it pins down what you're claiming — the specific expression, not a vague vibe — which is the first thing tested when someone argues your work is just "commonplace" building blocks.
Know the difference between inspiration and expression. Every creator borrows from what came before; the law allows it. What it does not allow is copying the specific, protected expression. Documenting your own independent creation — drafts, timestamps, session files, revision history — is cheap insurance, whether you are defending your work or asserting it against someone else.
Confirm you actually hold the right to sue before you need it. The least cinematic issue in this case may be the most important: whether the plaintiff owns enough to enforce. For an independent creator, that means knowing precisely which rights you hold, which you've licensed away, and whether you can act alone or need a co-owner's sign-off.
The uncomfortable truth underneath the spectacle is familiar: the creators who stay protected are not the ones with the catchiest hooks or the best ideas. They are the ones whose ownership was documented, registered, and traceable before a dispute — so that if a court ever has to decide who controls a work, the answer is already written down.
We'll track this docket as it develops. The next real signals will come as the parties fight over summary judgment and whether a jury ever hears "Flowers" and "When I Was Your Man" side by side — the moment a court will have to say how much of a pop song one owner can fence off.
