A catalogue's sale price is a multiple of its verifiable income, and metadata gaps quietly suppress both the income and the multiple. Here is how metadata cleanup increases music catalog value through two compounding routes - recovering royalties the catalogue is already earning, and making the rest provable to a buyer.
The short answer
Metadata cleanup increases music catalog value through two compounding routes. First, it recovers income the catalogue is already earning but not receiving - unmatched royalties, unregistered works, and misrouted payments. Second, it makes the remaining income verifiable, and verifiable income is what buyers actually pay multiples on. Because a catalogue's price is typically calculated as a multiple of its annual net income, every pound of recovered recurring income and every point of reduced buyer risk moves the final number in the same direction.
How music catalogues are valued
Buyers and valuers price a catalogue as a multiple of its net annual income, usually averaged over the last three years and adjusted for decay - how quickly the earnings are expected to decline. The multiple itself is not fixed. It moves with risk. A catalogue whose income can be traced line by line to registrations, agreements, and society statements commands a higher multiple than one where the buyer has to take the seller's word for it. Anything the buyer cannot verify gets discounted or excluded from the calculation entirely. The same logic applies to lenders in a catalogue refinancing - the advance is sized against income the lender can verify, not income the owner believes exists. That is why metadata sits at the centre of catalogue value - it is the layer that connects the money to the rights. A catalogue is not really a collection of songs for valuation purposes; it is a collection of income claims, and each claim is only as strong as the data behind it.
Route 1: recovered income that compounds
The first route is direct. Most established catalogues are earning money they never receive because the data describing the works and recordings is incomplete or inconsistent. Common causes include works never registered with a collection society, missing or conflicting ISWCs and ISRCs, writer splits that do not match across societies, and recordings whose performer or rights-holder line-up was never fully reported. The critical point for valuation is that recovered income of this kind is usually recurring, not a one-off windfall. If a work was unregistered in one territory, fixing the registration does not just release the backlog - it corrects every future distribution too. A catalogue earning an extra recurring amount per year is then worth that amount multiplied by whatever multiple the deal is priced at.
Where the unmatched money actually sits
Unclaimed royalties do not vanish - they sit in identifiable places, each with its own claims process. A metadata cleanup works through these pools systematically, matching the catalogue's works and recordings against what each society actually has on file:
- PRS for Music holds performance and mechanical income in the UK that cannot be matched to a registered work or the correct writer splits.
- PPL holds UK neighbouring rights income for recordings where the performer line-up or rights-holder data is missing or disputed.
- The MLC (the US Mechanical Licensing Collective) holds US streaming mechanicals for works it cannot match to a registered rights holder - one of the largest pools of unclaimed publishing money in the world.
- International societies and so-called black box distributions, where income that stays unmatched for long enough is eventually redistributed to other members rather than paid to the rightful owner.
Route 2: the verifiability premium
The second route is less visible but often worth more. During due diligence, a buyer traces reported income back to its source - the registration, the agreement, the society statement. Income that cannot be traced is treated as at risk, and at-risk income is either discounted or stripped out of the valuation model. Clean metadata reverses this. When every work has a verified ISWC, consistent splits across societies, and a documented chain of title, the buyer's diligence gets faster and their risk adjustment gets smaller. The seller is no longer asking the buyer to trust the numbers - the data proves them. That difference shows up directly in the multiple offered, and it also reduces the chance of a deal collapsing or being renegotiated late in the process. Sellers tend to focus on the income number because it is visible; buyers spend most of their attention on verifiability because it is where their downside lives. A cleanup addresses both sides of that conversation at once, which is why it is one of the few pre-sale actions that improves the base and the multiple simultaneously.
What a metadata cleanup actually involves
A proper cleanup is an audit followed by remediation, not a quick spreadsheet tidy. The core stages are:
- Building a master list of every work and recording, then reconciling it against distributor records, PRS for Music and other society registries, and neighbouring rights databases such as PPL's.
- Fixing identifiers - resolving missing or duplicate ISWCs and ISRCs, and correcting writer and performer data so the same work looks identical in every system.
- Re-registering works that were never registered, or registered incompletely, in the territories where they earn.
- Claiming funds held in suspense and unmatched accounts, including historical distributions at The MLC and international societies, before black box deadlines pass.
- Documenting the results so that every income line can be traced to a registration and an agreement - the pack a buyer's diligence team will ask for.
Who benefits most from cleanup
The uplift is largest where the gap between what a catalogue earns and what its data supports is widest:
- Estates, where registrations often still point at the deceased artist and successor rights were never properly recorded.
- Catalogues acquired in a previous deal and never audited afterwards - the metadata problems simply transferred with the assets.
- Labels with pre-digital back catalogue, where works were registered on paper systems and never fully migrated to modern identifiers.
- Artists who changed distributor one or more times, leaving orphaned releases, duplicate ISRCs, and broken payment routing behind.
When to clean up - before the valuation, not after
The order matters because of how the arithmetic works. Cleanup done before a valuation raises the income base and lowers the risk discount, so the improvement is multiplied through the deal price. Cleanup done after a sale hands that entire uplift to the buyer - which is precisely why sophisticated acquirers run metadata audits on catalogues they are bidding on. It also takes time. Society registrations, claims at PRS for Music, PPL, and The MLC, and split corrections can take months to work through and settle into statements. Starting the cleanup twelve months or more before a planned valuation, sale, or refinancing lets the recovered income appear in the trailing earnings a valuer will actually look at.
What metadata cleanup cannot do
Cleanup is not alchemy, and it is worth being honest about the limits. It cannot invent income - it can only recover money the catalogue has genuinely earned and make existing income provable. A catalogue with weak streaming numbers and no sync history will not become a premium asset because its ISWCs are tidy. Nor can cleanup fix a genuinely broken chain of title - if the underlying ownership is disputed, that is a legal problem, not a data problem, although a metadata audit will usually be what surfaces it. What cleanup reliably does is ensure that whatever the catalogue truly earns is collected in full and can withstand a buyer's scrutiny.
How to start
If you own or administer a catalogue and are weighing up a valuation, sale, or refinancing, the first step is to find out what the metadata currently supports and where income is leaking. Code Group Music audits catalogues against distributor records, society registries, and neighbouring rights databases, then remediates registrations and pursues unclaimed funds. Publishing administration runs on a commission basis, and Metadata Administration is quoted per catalogue - there are no published price lists because no two catalogues carry the same workload.

Frequently Asked Questions
How is a music catalogue valued?
A catalogue is typically valued as a multiple of its net annual income, averaged over recent years and adjusted for expected decay. The multiple moves with risk - income that can be traced to verified registrations and clean chain of title supports a higher multiple, while income a buyer cannot verify is discounted or excluded from the calculation altogether.
Does bad metadata reduce music catalog value?
Yes, in two ways. Missing registrations, wrong identifiers, and mismatched splits mean some royalties are never collected, so the income base the multiple is applied to is lower than it should be. Separately, income that cannot be traced to clean data is treated as risky during due diligence, which pushes the offered multiple down or removes that income from the deal model.
What does music metadata cleanup involve?
It starts with an audit - reconciling every work and recording against distributor records, PRS for Music, PPL, and international registries. Remediation then fixes missing or duplicate ISWCs and ISRCs, corrects writer and performer splits, re-registers works in territories where they earn, and files claims for money held in suspense accounts, including unmatched funds at The MLC.
How long does metadata cleanup take?
For an established catalogue, expect months rather than weeks. The audit itself can be relatively quick, but society re-registrations, split corrections, and unmatched claims at PRS for Music, PPL, and The MLC each run on the societies' own processing timelines. If a valuation or sale is planned, starting at least twelve months ahead lets recovered income show up in the earnings a valuer reviews.
