{"id":3756,"slug":"african-own-chart-share-change-four-markets-aug-sep-2026","title":"How the African share of each of Spotify’s four African daily charts moved, 13 August to 7 September 2026","source":"Computed from this desk's spotify-four-african-charts-african-share-series-2026 dataset","source_url":"https:\/\/kworb.net\/spotify\/","source_type":"computed","method":"One row per market. first_share_pct and last_share_pct are the first and last of the 16 collection dates in the underlying series, 2026-08-13 and 2026-09-07. change_pts is the difference in percentage points and change_rel_pct that difference relative to the first reading. An endpoint comparison is hostage to whichever day sits at each end, so first_half_mean_pct is the unweighted mean of the first eight collection dates and second_half_mean_pct the mean of the last eight, with half_change_pts their difference; that is the more conservative reading and the one to prefer. steps_fell, steps_rose and steps_flat count the date-to-date transitions and sum to steps_total, which is 15 for every market. african_streams and chart_streams columns give the numerator and the denominator separately on the two endpoint dates, with their own percentage changes, so a reader can see whether a share moved because African music moved or because the rest of the chart did. This desk's Spotify chart collector retains the most recent full 76-market snapshots of the daily Top 200 as published by kworb.net. This dataset was built on 2026-09-07 from every snapshot on disk: 2026-08-13, 2026-08-17, 2026-08-20, 2026-08-21, 2026-08-22, 2026-08-24, 2026-08-25, 2026-08-27, 2026-08-28, 2026-08-30, 2026-08-31, 2026-09-01, 2026-09-02, 2026-09-04, 2026-09-06 and 2026-09-07. Gaps between listed dates are collection gaps, not zeros, and the intervals are uneven. For each date and each of the four markets Spotify publishes a daily chart for in Africa (Nigeria, Egypt, Morocco, South Africa), every entry on that market's Top 200 was summed, and the portion credited to lead artists whose registered country of origin is on the African continent was divided by the market total. Origin is applied as currently registered in this desk's roster, to every date, so a later correction moves the whole series rather than only future points. Two artists flagged as classified by name search and relevant to these four charts, Samthing Soweto (South Africa) and Cheb Amrou (Morocco), were checked against their charting recordings and confirmed against published biography before this build. Chart streams are a sample of consumption inside a market's daily Top 200, not a full accounting of streaming in that market, and a share of the Top 200 is not a share of a country's listening. On 2026-08-28 the upstream source served a chart identical in every position, track and stream count to 2026-08-27 for 44 of 76 markets, Egypt among them; Nigeria, Morocco and South Africa differed. That date is retained and disclosed rather than dropped, and it registers as a flat step for Egypt, not a fall. Five columns ending _abs restate the signed change columns as magnitudes, so that the size of a move can be read and quoted without its direction; the direction is in the signed column beside it.","unit":"pct","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
