An artist counts as having African chart presence if it appears at least once, on any of those 20 dates, in the snapshot rows for Egypt, Morocco, Nigeria or South Africa's own daily chart, the four African markets this desk's panel covers. Before this run's corrections the charted count was 309; the eight artists this run resolved, detailed in roster-corrections-15-september-2026, were all inside that 309, so removing them lowers the charted count to 301 without changing the never-charted count.","unit":"artists","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.","confidence":"high","retrieved":"2026-09-15 13:00:00","n":4,"first_party":0,"columns":[{"key":"measure","label":"Measure","type":"text"},{"key":"artists","label":"Artists","type":"number"}],"rows":[{"measure":"Origin-unresolved artists checked against the 20 kept chart snapshots, after this run's corrections","artists":1904},{"measure":"Never appeared on Egypt, Morocco, Nigeria or South Africa's own chart in that window","artists":1603},{"measure":"Appeared on at least one of those four charts at least once, after this run's corrections","artists":301},{"measure":"Appeared on at least one of those four charts at least once, before this run's corrections","artists":309}]}
