{"id":9552,"slug":"no1-churn-across-8-feeds-16aug-09nov-2026","title":"Turnover at number one, pooled across all 8 daily chart feeds this desk collects for Africa, 16 August to 9 November 2026","source":"This desk's own chart collection (afw_chart_snapshot \/ afw_chart_entry)","source_url":"","source_type":"computed","method":"This desk collects a daily chart from 8 source\/chart-type combinations covering African markets: Spotify songs (4 markets), Apple Music songs, albums and music-videos (41 markets each), Shazam songs (15 markets), Deezer songs (9 markets), iTunes songs (17 markets) and this desk's own composite ranking blending the available feeds per market (42 markets). Every snapshot in the store runs 16 August to 9 November 2026 (85 calendar dates); Apple's three chart types were actually captured on 83 of those dates in every market and Deezer, Shazam, iTunes and the composite on 85 (all share the same calendar window, collection gaps differ). For every (source, chart_type, country) combination, every row at chart position 1 was pulled and sorted by date. A 'change' is counted on any date where the (title, artist) pair at position 1, lowercased, differs from the pair at position 1 the previous collected date for that market; the first date in a market's series is not counted as a change. market_days is the sum of distinct collected dates across all markets in that source\/chart_type group (so a group with more markets or more collection dates has a larger market_days total; it is a sum of day-counts, not a single calendar count). changes is the sum of change events across all markets in the group. churn_rate_pct is changes divided by market_days, i.e. the percentage of observed chart-days on which #1 was a different title\/artist pair than the day before. mean_reign_days is market_days divided by changes, i.e. the average length in days of an unbroken run at #1, pooling all reigns in all markets in that group together (not a per-market average, a pooled one). distinct_no1s counts distinct (title, artist) pairs that held #1 at least once anywhere in the group. All figures use exact string identity on title and artist as printed on the chart (lowercased only); a sensitivity check using stricter normalisation (stripping punctuation and parenthetical\/feat credits) is registered separately and moves every churn_rate_pct by less than 1 percentage point, so the headline is not an artefact of cosmetic title formatting. ratio_to_shazam_churn is each row's churn_rate_pct divided by Shazam's (the lowest churn in the set), so Shazam's own row is exactly 1.","unit":"count","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
