{"id":5077,"slug":"african-export-column-persistent-departed-arrived-13aug-to-12sep-2026","title":"Spotify’s African export column split into artists that persisted, departed and arrived, 13 August to 12 September 2026","source":"Computed from this desk's african-export-column-persistence-13aug-to-12sep-2026","source_url":"https:\/\/kworb.net\/spotify\/","source_type":"computed","method":"A decomposition of the six artist-level export breakdowns this desk holds, run entirely inside african-export-column-persistence-13aug-to-12sep-2026 so that every column shares one origin vintage and one export definition. as_recorded is the sum of all fifteen artists on each date, which reproduces each date's registered composition total. excl_calema removes Calema on every date, because this desk's roster now registers Calema as Portuguese rather than Sao Tomean and the act is therefore outside the African population as currently defined; the removal is applied to every date including the historical ones, so that a change of definition is not reported as a change in the charts. The remaining fourteen artists are then partitioned by their two end dates alone, with no hand-picking: persistent_seven are the seven non-zero on both 13 August and 12 September, departed_four are the four non-zero on 13 August and zero on 12 September (DopeNation, Victony, Rema and Shimza), arrived_three are the three zero on 13 August and non-zero on 12 September (TUL8TE, Marwan Pablo and Noura). The three parts sum exactly to excl_calema on every one of the six dates and the build aborts if they do not. persistent_change_vs_13aug_pct and excl_calema_change_vs_13aug_pct index each series to its own 13 August value. The partition is defined by the end dates, so an artist scoring zero on an intermediate date still sits in the group its endpoints put it in. This decomposition cannot say why an artist stopped charting outside Africa, only that it did.","unit":"streams","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
