A song plays. How does Data make sure the artist gets paid?

When a song plays on the radio, in a restaurant, at a concert, or on a streaming platform, someone has to answer a practical question: who should be paid?

The answer is rarely as simple as counting the number of times a song was played. A royalty payment can depend on where the music was used, the size of the audience, the time of day, the type of use, and the people who helped create the work.

At the guest speaker session “Who Gets the Cent? How a Collection Society Turns Billions of Data Points into Music Royalty Payouts,” hosted by Parami University on October 22, Dr. Christina Hans gave students an inside look at how music royalties are collected and distributed. As the technical lead of the royalty distribution system at GEMA, Germany’s music copyright collection society, she explained how a traditional institution leverages data systems to process vast amounts of information and distribute more than one billion euros in royalties to music creators and rights holders.

Her talk connected two subjects that can seem far apart: the creative work of making music and the technical work of organizing data. It also showed how a small payment to one artist can depend on a much larger system.

A song can create many payments

Collection societies, also called collecting societies or collective management organizations, help manage copyright payments for music creators. They collect licensing money from different uses of music and distribute it to the people who are entitled to receive it.

Those people may include composers, lyricists, and music publishers. An artist may not need to join every collection society around the world, either. Societies can work together across borders. As Dr. Hans explained, "You don’t have to be a member of every collection society in the world, but they all collaborate together."

That cooperation matters when music travels. If a song by a Myanmar artist is played in another country, the local society may collect the money and send it to the society that represents the artist. The payment can then reach the creator through the relevant system.

But the amount is not the same in every situation. A song used in a concert, on television, on radio, or through a streaming service may be valued differently because each use brings in different licensing income.

"For online plays, you get a lot less money than for a concert," Dr. Hans said, while explaining that the amount collected through licensing fees helps shape the final payment.

The calculation can become even more detailed for television. Dr. Christina Hans gave examples of factors such as the size of the audience and the time of day. Music played during the day may receive a different weight from music played at night. Music used as an opening theme may also be treated differently from music heard in the middle of a program.

In other words, royalty distribution is not only about whether a song was played. It is also about how, where, and for whom it was played.

Why the system needs so much data

GEMA processes huge volumes of information each year. The system must connect usage reports with songs, creators, publishers, and the rules used to calculate payments.

Some uses are easy to document. A concert may have a set list that identifies the songs performed. In that case, the society has a clear record to work with.

Other situations are harder. It may not be practical or financially possible to record every piece of music played in every place. Dr. Hans described the solution this way: “A collective distribution is used whenever it is a bit unclear what was played, or it is not really economically feasible to collect all the data on what was played.”

This is where the data infrastructure becomes important. The system has to receive information from different sources, clean and match the records, apply the correct rules, and calculate payments at scale. It also needs to continue working when the data is incomplete, delayed, or difficult to compare.

For students interested in data science, the example offered a useful lesson. Data work is not limited to dashboards or predictions. It can also support decisions that affect people’s income and the way a creative industry operates.

Thousands of rules behind one payment

Dr. Christina Hans explained that the distribution system contains a large number of detailed rules. Some of those rules are hard-coded, which means they are written directly into the system’s logic.

She compared the rules to a series of “if” statements: if a work is used in a particular way, under particular conditions, then the system applies a particular result. The rules can account for differences between types of music use, contributors, and reported performances.

That does not mean the system can change itself whenever music trends change. New rules require discussion and approval. Dr. Hans explained that proposals must go through the membership association before they can be adopted.

This point led to one of the most important questions from the audience: how can artists hold a collection society accountable if they do not understand how their royalties are calculated?

The question highlighted a wider challenge. A system can be technically accurate and still be difficult for the people affected by it to understand. Clear explanations, accessible records and responsible decision-making matter alongside the technology.

The people behind the data

The conversation also brought the focus back to creators. GEMA has more than 100,000 members, including composers, lyricists and publishers. Each person may have a different role in a work, and each work may be used in many different settings.

For Dr. Christina Hans, the purpose of all the data and infrastructure is not simply to operate a large machine. “I mostly talked about royalties just as a format for musicians making a living wage from their art, and also from their art through all sorts of different platforms,” she said.

That sentence helped bring the technical discussion into focus. Behind every record is a person who wrote, performed, arranged, or published music. Behind every payment is a set of choices about how creative work should be valued.

Students asked about international regulations, music played across borders, streaming platforms, data access, and the role of data scientists in a system built around established rules. One question also asked whether a similar collection society could one day be created in Myanmar.

The variety of questions showed how quickly the topic moved beyond music. It became a conversation about technology, fairness, international cooperation and the systems that shape people’s livelihoods.

What students took away

The session offered a clear message for anyone working with data: scale does not remove the need for judgment. A system can process billions of data points, but people still have to decide which rules are fair, which information is reliable, and how the results should be explained.

It also offered a message for artists and listeners. Every time music is used, there is a network behind it: creators, publishers, collection societies, technology platforms, and data teams. Understanding that network makes the journey from a song being played to a royalty being paid a little less mysterious.

And the cent? It does not belong to one system or one person by default. It follows the rules, the records, and the people whose work made the music possible.
