Circa 40
Every measured song, ranked by the share of Circa 40's own players who named it correctly — never compared against a different artist's catalogue.
Catalogue recognition
Share of this artist's own players who named each song correctly. Thin marks show the 95% interval.
How fast people finish
A run is ten rounds on Circa 40. This is how quickly players get all ten right.
Not enough verified complete runs on Circa 40 yet. A board needs at least 50 verified runs and 20 verified 10-out-of-10 finishes, so that a record is not set by a handful of people. Play the quiz and it will appear.
Recognition vs streams
What streaming popularity predicts, against what players actually did.
Pizza — 11% of this artist's own players name it correctly against 39% predicted by its streaming popularity (28 points below, n=366). Shadow Flow 8 Ball — 10% of this artist's own players name it correctly against 38% predicted by its streaming popularity (27 points below, n=340).
Markets
Where this artist is played more than their global share predicts.
No market clears the floor for this artist yet. A country is published only with enough distinct players behind it that one small community cannot move the number.
Taste neighbours
Artists whose players overlap most, learned from who plays whom — useful for support slots and playlist seeding.
Not enough distinct-listener overlap to publish neighbours for this artist yet. For a very large act nearly every scene overlaps a little, which is noise, not a signal — we would rather show nothing than publish a guess.
What this is, and is not
Who is measured. Muzify players who chose this artist in the app — mostly existing fans, not a random public sample. Read it as "how well do their own listeners know the catalogue", never as national awareness.
What "named it" means. One clip, four options, a five-second clock. Chance alone is 25%.
Floors. A song appears only above 200 answers; a market only above 25,000 plays. Everything else is withheld rather than shown thin.
Player counts are bands, never exact figures.
