{"id":3764,"slug":"chart-snapshot-duplication-check-27-28-august-2026","title":"Collection integrity check: Spotify charts served identical on two consecutive collection dates, 27 and 28 August 2026","source":"Computed from this desk's own retained chart snapshots for 2026-08-27 and 2026-08-28","source_url":"https:\/\/kworb.net\/spotify\/","source_type":"computed","method":"Every chart in this desk's 2026-08-27 snapshot was compared position by position against the same chart in the 2026-08-28 snapshot, matching on chart position, track identifier and stream count. A chart is counted as identical only where all three matched at all 200 places. The comparison covers the 75 country charts Spotify publishes plus Spotify's own global chart, 76 in total. This is a check on the desk's own collection, run because Egypt's African share was flat to two decimal places across those two dates and a flat reading on a volatile series is more often a collection fault than a finding. The identical charts include Egypt, the United States, the United Kingdom, Germany, France, Brazil, Japan and India; Nigeria, Morocco and South Africa were not among them. The check cannot say whether the upstream source republished a stale page or whether Spotify itself did not update, and no cause is claimed.","unit":"charts","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
