{"id":9006,"slug":"apple-chart-surface-composition-41-african-markets-2026","title":"Composition of Apple Music’s songs chart and music-videos chart across 41 African markets, 16 August to 3 November 2026","source":"This desk's own Apple Music daily chart collection, plus this desk's own artist-origin registry","source_url":"","source_type":"computed","method":"Built on the same 2,411 paired country-days across 41 African markets and 77 dates as the overlap table, with the same lead-artist normalisation and the same per-country-day de-duplication. distinct_artists counts normalised lead artists appearing at least once on that surface. artists_20plus_markets and artists_one_market_only count those artists by the number of distinct African markets they reached on that surface. artist_slots is the sum of per-country-day de-duplicated lead-artist counts. confirmed_african_slots counts the subset of those slots whose normalised lead-artist string exactly matches a name this desk's own origin registry has already resolved to an African country of origin with an african flag of 1. That registry holds 174 such names and was built from Spotify's four African daily charts, so it covers Nigeria, South Africa, Egypt, Morocco, Algeria, Angola, Ghana, Tunisia and Cameroon only: confirmed_african_pct is therefore a floor on each surface and not a measurement of African content, and it is comparable between the two surfaces only because the same 174-name test is applied identically to both. Exact string matching means an artist credited under a different spelling than the registry holds is counted as unconfirmed. chart_entries is the raw number of chart rows collected on that surface across the same paired country-days, and entries_per_artist is chart_entries divided by artist_slots: it measures how many chart positions the average artist holds at once on that surface, and it is reported because it is the mechanical reason the two surfaces carry different artist-slot totals from a near-identical number of chart rows.","unit":"count","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
