Streams and memory disagree
Left: how many players should name a song quickly, judging by how much it is streamed. Right: how many actually did. Lines that climb are songs people know better than their streams suggest.
Known beyond its streams
Fans carry these in their heads. Cult favourites, deep cuts and scene anthems.
Bladee, “Amygdala”
Streamed beyond recognition
Big streaming numbers, yet players can't place the song when it plays.
Michael Jackson, “You Are Not Alone”
Every country has its own obsession
How many times more a country plays an artist than that artist's global share predicts. At least 20 different players stand behind every number, so one superfan can't move the map.

Who plays
Players choose the artist, so most are fans. Chapter 01 compares songs within one artist only.
What "quick" means
Right, and faster than the typical correct answer (about four seconds from the start of the round, clip loading included).
The model
Song difficulty comes from an item-response model that beats per-song averages on held-out sessions (AUC 0.75 vs 0.69).
Privacy
Sessions are salted hashes. No one is identifiable, and every published cell has a minimum player count.
