Chris Brown's "Party" Producer Sues Sony and the Complaint Centers on an Audit Waiver
News / Money Moves | Power JDM The Beat
Producer Ishmael Sadiq Montague, known professionally as ISM and credited as a producer on Chris Brown’s “Party,” has sued Sony Music Entertainment in federal court in New York. The complaint, filed October 16, 2026, seeks at least $1,247,500 and centers on two connected allegations: that Sony accounted for Montague’s producer royalties at half the rate he says his agreement provides, and that the company delayed redirecting royalty payments during a sale of his royalty interests.
Montague’s claims have not been proven, and no ruling has been issued. Music Business Worldwide, Digital Music News and AllHipHop have reported on the complaint. The cited coverage does not report a public court response from Sony. The complaint says Sony’s in-house counsel denied liability before the suit was filed and described the matter as “fully resolved.” That statement is reported here as an account in the filing, not as a public court response.
The case concerns “Party,” the 2016 recording featuring Usher and Gucci Mane. Chris Brown is not a defendant in the lawsuit.
The alleged rate difference
According to the complaint, a 2016 producer agreement set a 3% royalty for the producers, with Montague entitled to 1.5% after a split with co-producer A1. Montague alleges that Sony instead applied a 0.75% rate to his account. Half the rate he says he was owed.
Music Business Worldwide and Digital Music News report that Montague’s complaint says a third-party review identified the difference in July 2026, and that he notified Sony in writing on August 25. The filing describes an approximately 50% underpayment for the most recent statement period. It does not state that the $1,247,500 sought in the suit is a calculation of the alleged royalty shortfall. Instead, Montague says the amount concerns damages he attributes to the alleged conduct surrounding the royalty transfer and other claims.
The distinction matters: a royalty rate is applied according to the contract’s terms and the accounting base defined by the agreement. A difference between 0.75% and 1.5% is a major discrepancy in the stated rate, but determining what is owed may also require reviewing the agreement, statements, deductions, payment history and the precise royalty base.
Why the audit waiver is central
The complaint alleges that Montague and his company agreed in June 2026 to sell royalty interests in several recordings, including “Party,” to Xposure Music Holdings. According to the filing, payments were supposed to be redirected to the buyer beginning September 1. Montague alleges that Sony delayed the payee change for about six weeks while insisting he use a letter of direction containing an acknowledgment that the payee had no right to audit Sony or its affiliates.
An audit waiver generally means giving up some or all of a contractual right to examine or challenge a company’s royalty records. The specific effect depends on the language, the agreement and the circumstances. A waiver can be narrow or broad: it may apply to a particular statement or period, or it may cover a wider set of accounts, companies or claims. Once signed, it can make it harder, or potentially impossible, to investigate an accounting dispute, depending on its terms and applicable law.
In this case, Montague alleges that Sony described the requested form as fixed company policy, while an alternate assignment form without the disputed audit language was available. The complaint says he signed the alternate form on August 29, and that the executed document contained no release or waiver. Those details remain allegations in pending litigation.
What producers and artists can learn
Know your contractual rate before statements arrive
Save the signed producer agreement, amendments and any documents that explain how a royalty is divided among collaborators. Confirm the applicable rate, who receives it, how splits are calculated and what accounting base applies. Knowing the terms in advance makes it easier to spot a discrepancy when statements come in.
Keep your own ledger and compare against statements
Track each release, royalty period, rate, payment date and amount received. Keep statements and payment records together with the relevant contracts. A ledger does not replace a professional review, but it can help identify questions early and show how a concern developed over time.
Never sign a waiver under time pressure tied to a payment
If a document says you are giving up audit rights, releasing claims or accepting an account as final, pause and read the language carefully. Ask what rights are being waived, which accounts and periods are covered, and whether signing is required for an unrelated payment or transfer. A deadline connected to money owed can make it difficult to assess a document clearly.
Audit rights expire, so calendar them
Some agreements set time limits for raising accounting objections or requesting an audit. Those deadlines can differ by contract and jurisdiction. Note the relevant dates when statements arrive, and check the agreement rather than assuming a dispute can be raised at any time.
Get an entertainment attorney before waiving audit rights
A qualified entertainment attorney can review the contract and proposed waiver, explain what rights may be affected, and help distinguish an administrative payee change from a settlement or release. This is especially important when several companies, catalogs or royalty accounts appear in the same document.
Publishing
Publishing income and recording royalties are separate rights streams, and a producer should check what each agreement covers. The complaint in this case concerns producer royalties associated with a sound recording; it does not establish a dispute about songwriting or publishing rights.
Artists who own or control their master recordings may also collect eligible SoundExchange royalties when their music is played on qualifying non-interactive digital services.
Radio-friendly talking points: 5- to 10-minute segment cues
- Minute 0–1: Set the facts. A producer filed suit against Sony over alleged royalty underpayment and delays involving a payee change. Emphasize that the claims are allegations and there has been no ruling.
- Minute 1–3: Explain the rate math. The complaint says Montague was owed 1.5% after a producer split but was accounted for at 0.75%. Explain that the contract and royalty base determine the final accounting.
- Minute 3–5: Define an audit waiver. Discuss how a waiver may limit the ability to examine royalty records, and why the exact wording and scope matter.
- Minute 5–7: Talk through the pressure point. The complaint alleges the requested waiver language was tied to a payment-direction process. Discuss why musicians should slow down when a document and a pending payment arrive together.
- Minute 7–9: Share practical recordkeeping habits. Keep agreements, royalty statements, payment records and a dated ledger in one place. Calendar objection and audit deadlines.
- Minute 9–10: Close with the case status. Montague seeks damages, an accounting and a court-supervised audit. The dispute remains pending; the allegations have not been adjudicated.
The filing asks the court for at least $1,247,500, punitive damages on certain claims, an accounting and a court-supervised audit. The complaint says the damages sought are not simply a calculation of unpaid royalties. Whether any of Montague’s claims succeed, and whether an audit or payment is ultimately ordered, will depend on the court process and evidence.
