Comparing where music tastes overlap and split across 20 countries' Spotify charts
What Is It About?
Streaming platforms like Spotify made the same music accessible to a majority of countries in our world. But does that mean daily music habits also tend to be similar? This project looks at a snapshot, September 1st 2026, and compares the Daily Top 100 Spotify charts of 20 countries.
Introducing the Chart
Each bar below stands for one of the 20 countries in this comparison. Right now they all look the same, each one showing a placeholder value of 100. As the story continues, the height of each bar will change depending on what is being compared at that point.
Reach
One way to compare the charts is to look at how many countries share the same song on a given day. The song that reached the most countries on September 1st 2026 only appeared in 11 of the 20. Five different songs were tied at that number. The bars now show one of them, The One That Got Away by Katy Perry, and its rank in each country it charts in. Click through the songs on the right side to see the other 4 and their rank.
Unmatched Music Taste
So no single song reaches every country. But that raises a different question: how much of a country's own Top 100 doesn't appear anywhere else at all? The bars now show the percentage of each country's Top 100 that does not appear in any other country's chart. This ranges from 99 percent in Egypt to 11 percent in Switzerland.
The Most Unique One
Egypt has the highest share of country-exclusive songs in the set, at 99 percent. Its own number 1 song, Garee2a Awy by TUL8TE and COLORS, does not appear on any other country's chart.
The Other Local #1-Countries
Egypt is not the only country whose top song stays entirely local. The same is true for Brazil, Finland, Iceland, Italy, Japan, Poland, Romania, South Africa, and South Korea, half of the 20 countries in this comparison. Click through the player to listen to these unique #1 hits of September 1st.
The Least Unique One
At the other end of the scale is Switzerland, where only 11 percent of the Top 100 is exclusive to the country itself, the lowest of all 20.
Dai Dai
Switzerland's own number 1, Dai Dai by Shakira and Burna Boy, shows why: this song also charts at number 1 in Austria, and number 4 in Germany. The bars now show which rank it reached in each country.
Switzerland's Connections
The bars now show how many of each country's 100 songs are also on Switzerland's chart specifically. Germany and Austria stand out clearly, 65 and 63 out of 100, far more than anyone else.
Austria and Germany
Austria and Germany's connection is the strongest of any pair in the set, 71 shared songs, even more than either has with Switzerland. Dai Dai is one of them, but their charts overlap far beyond just that one song. The bars now show how many songs each country shares with Germany specifically.
Crossing Borders: ISSA
Some of that overlap comes down to specific artists who are popular across the whole region. Sido's song ISSA charts at number 3 in Germany, number 12 in Austria, and number 16 in Switzerland, the entire DACH region at once. The bars now show the song's rank in each country instead.
Crossing Borders: BOSTON
This bridging pattern isn't unique to the DACH cluster from before. STELLA LEFTY's song Boston charts at number 10 in Australia, number 15 in the UK, and number 16 in the USA, and nowhere else.
Crossing Borders: BbY WOW
BbY WOW by KAROL G, Judeline, and rusowsky spans an even wider mix, charting number 1 in both Mexico and Peru at the same time, and also at number 78 in Switzerland and number 3 in the USA.
Not Crossing Borders
Not every country connects this way. Egypt's chart is so exclusive it shares zero songs with 17 of the other 19 countries. Japan is nearly as isolated, sharing zero with 16. The bars now show each country's zero-overlap count instead. That means they show with how many of the other 19 each shares no songs with at all.
Market Size
Let's take a look at another angle of the countries' Top 100 chart snapshots now: the amount of streams each one got. The bars now show each country's total streams, on a logarithmic scale since they range so widely: from about 49 million in the USA to about 167 thousand in Iceland, a 295 times difference.
Mexico and Brazil
Mexico and Brazil are the 2nd and 3rd biggest markets in the set by total streams. Both are also among the most locally-driven charts we saw earlier, 76 and 97 percent exclusive. Streaming volume and how unique a country's taste is turn out to be two separate things: even huge markets like Mexico and Brazil can be almost entirely local.
In Summary
Streaming made the same music accessible almost everywhere. But on this one day, most countries still show clear borders in what actually overlaps. Even the widest-reaching songs only crossed into 11 of the 20 countries. A few clusters of countries share a lot with each other, and a few individual songs bridge others together. But most countries barely overlap with anyone else in this set, no matter how much they're streaming. This is only a snapshot, though. With a different day, a longer timespan, a different set of countries, or a different platform than Spotify, this could all look very different.
