"Stefania" and "Teresa & Maria" share a composer and a stage. Both are Kalush-family Eurovision entries, both charted internationally, and neither charted the way the other one did. "Stefania" reached number 85 on the Billboard Global 200 in 2022. "Teresa & Maria" reached number 130 on Billboard Global Excl. US in 2024, a different chart that Stefania never appears on at all. Two songs from the same catalog, measured by the same publication, ended up on two rulebooks. That gap is normal, and it says something engineers and composers rarely get told plainly: a chart position is not a single ladder with one set of rungs.
Which chart did each song actually reach?
"Stefania" (Kalush Orchestra, composed and produced by Anton Chilibi) peaked at number 38 on the UK Singles Chart and number 2 on the US World Digital Song Sales chart, alongside number 85 on the Billboard Global 200. "Teresa & Maria" (Wikipedia), composed by Chilibi and Ivan Klymenko for alyona alyona and Jerry Heil, peaked at number 1 on Ukraine Airplay and number 2 in Lithuania, and its one Billboard entry is number 130 on Global Excl. US. The Global 200 and Global Excl. US are not tiers of the same list. They are two different charts with two different eligible markets, published in the same magazine under similar-looking names.
What actually separates the Global 200 from Global Excl. US?
The Global 200 folds in US streaming, sales and radio data alongside more than 200 other territories. Global Excl. US runs the identical idea with every US data point removed, built specifically so a song's international footprint can be judged without a single dominant market skewing it. A song can lead one and be absent from the other for the same reason two rulers can measure the same wall and report different numbers: they are not calibrated to the same starting point.
How did Billboard just change what counts as a "stream," anyway?
In January 2026, Billboard's domestic Hot 100 and Billboard 200 changed their own stream weighting: one album sale now equals 1,000 paid on-demand streams or 2,500 ad-supported streams, tightening the paid-to-free ratio from 1-to-3 down to 1-to-2.5. Music Business Worldwide reported the change as a deliberate shift toward rewarding deliberate, paid listening over free plays. That formula governs the domestic charts specifically. The Global charts run their own separate math, built around a comparable but not identical split between premium and ad-supported streams. Two charts from the same publisher, same month, running two different formulas.
What does a certification measure that a chart position doesn't?
"Stefania" was certified platinum in Poland in 2024, two years after release. "Teresa & Maria" was certified gold in Poland and gold for streaming in Greece in 2025. A certification is not a snapshot of one week. It is a cumulative, audited count of sales-equivalent units crossing a fixed national threshold, set by that country's own industry body, with no expiry and no chart position attached. A song can be certified without ever cracking a weekly chart, and a song can top a weekly chart without ever reaching a certification threshold in a smaller market. They are answering different questions: one asks what happened this week, the other asks what happened, total, eventually.
What did the televote already measure, before any of this?
Eurovision's own scoreboard is a third system again. "Stefania" won with 631 points, including 439 from the televote, the highest televote total in the contest's history at that point. "Teresa & Maria" placed third with 453 points two years later. That vote splits evenly between a public phone, app and SMS televote and a panel of national juries, each side scored separately and converted into the same 1-8, 10, 12 point scale before the two totals combine into one ranking. It closes in a single broadcast and has nothing to do with streams, sales or certifications afterward. A song can dominate the televote and still take two years to reach a certification threshold, which is exactly what "Stefania" did.
What happens when the measurement is radio airplay instead?
Despite landing on two different Billboard charts, "Stefania" and "Teresa & Maria" both topped the same airplay ranking: TopHit's Ukraine Airplay chart, at number 1 each. Airplay counts monitored radio spins, not purchases or on-demand plays, licensed through its own separate data provider, unconnected to the sales-and-streaming math behind either Global chart. On that fifth measurement, the two songs are identical, both number 1, at the same time as one sits at 85 on one Billboard chart and the other sits at 130 on a different one entirely. A catalog can top one system, land mid-table on a second, and stay off a third altogether, with every one of those readings accurate at once.
What should this mean for how a credit gets described?
Four systems, four different questions: a weekly chart asks what sold and streamed in a specific window in a specific set of markets, a certification asks what accumulated over time against a fixed bar, a contest vote asks what an audience and a jury preferred on one night, and a raw engagement number from any single platform answers a narrower question still. Naming the actual metric, the chart it came from, and the date attached to it holds up under a fact check. A flat claim that a song "charted" or "went viral," with no metric named, is the first thing an editor or a supervisor tests and the first thing that fails.
