Show HN: Check if any of the $656M in unclaimed royalties at The MLC is yours

The post is a launch for a self-service site that lets anyone paste in a Spotify artist link, compare that catalog against The Mechanical Licensing Collective’s bulk database, and see which tracks are fully claimed, partially claimed, unmatched, or missing. The point is not general royalty tracking. It is specifically about U.S. digital streaming mechanical royalties on the publishing side, which The MLC has been holding since the Music Modernization Act set up the system. The author says more than $656 million is sitting there and that beginning in January 2027, unclaimed money starts getting paid out by market share to rights holders already in the system. That creates a deadline for songwriters and publishers to fix registration and metadata issues before leftover money drifts to bigger incumbents.

If you work with musicians, labels, or creator platforms, this is a concrete reminder that rights metadata and registration still directly determine who gets paid. Treat publishing data quality as an operational problem now, not an admin cleanup task you can defer past the 2027 redistribution window.

Discussion mood

Mostly positive and appreciative. People believed the underlying royalties problem is real, liked that the tool is free and actionable, and shared their own frustration with music rights administration. The negative notes were practical: weak explanation for newcomers, rate-limit outages under load, occasional wrong artist matching, and skepticism about how precise the money estimates can be.

Key insights

  1. 01

    DIY publishing collection is still brutal

    Trying to collect publishing income as an independent artist still looks like clerical warfare, especially once international rights enter the picture. That turns the tool from a nice search widget into evidence that a large chunk of missing money persists because the system is too hard for ordinary creators to navigate correctly.

    If your product touches creator payouts, assume many users have not done the underlying rights setup at all. Build for incomplete registrations and missing metadata, not for a clean rights graph that exists only on paper.

    The missing money sits in publishing, not masters

    The key distinction is that a song has separate rights for the sound recording and the underlying composition. A track can be live on Spotify through a label or distributor while the songwriter-side mechanical royalties are still unmatched or unclaimed, because those flows run through a different licensing and collection stack. That explains why commenters who assumed the distributor should already handle payment were aiming at the wrong part of the pipeline.

    If you advise artists or build music software, separate master and publishing workflows from day one. A distributor dashboard is not proof that composition-side royalties are covered.

    Use the estimate as triage, not valuation

    The monetary range is credible only in a narrow sense. The lower bound uses The MLC’s own unmatched-value buckets, but the broader estimate depends on Spotify counts and guesses about other services, U.S. share, and changing rates. That makes the output useful for deciding whether a catalog deserves follow-up, but not for pricing the exact recovery opportunity.

    Do not treat consumer-facing estimates like settled receivables. Use them to prioritize outreach and cleanup, then verify with source systems before making financial decisions.

    Public data exists but it is expensive and heavy

    Reproducing this yourself is possible, but not lightweight. The MLC bulk feed costs money, arrives as roughly 400 gigabytes of raw TSV files each week, and needs a real ingestion and indexing pipeline before it becomes searchable. That detail explains why a simple public lookup tool did not already exist despite the underlying data being technically available.

    There is a real product wedge in turning open or quasi-open industry data into usable workflows. The moat is often boring infrastructure work, not exclusive access.

Against the grain

  1. 01

    Name collisions can break trust fast

    A user searched for an album and got results from a different artist with the same name. That is exactly the kind of metadata ambiguity this product is supposed to clarify, so even a single bad match lands harder than a normal search bug and makes the rest of the report feel suspect.

    For rights and finance tools, invest early in identity resolution and confidence indicators. If an entity match is fuzzy, say so before showing money attached to it.

    No-source data handling will worry some users

    One objection was not about royalties at all. It was about whether the site is collecting search data for the operator’s own business, especially since the code is not open and the product sits on top of a broader commercial stack. In a niche industry with lots of mistrust, that concern is predictable even if the data sources are public.

    If your tool doubles as lead generation, be explicit about data use and business incentives. That lowers friction with skeptical users before they decide the whole product is a funnel.
