Core countries are Nigeria, Egypt, Morocco and South Africa, the only four present on every one of the first six dates measured; periphery_countries lists every other country with an artist that day. periphery_share_pct is the combined daily-stream share of those periphery countries, and core_share_pct is 100 minus it; artists_core4_pct is the share of the 50-artist panel held by the four core countries. The six prior rows are unchanged from the earlier dataset. The 2 October row is new: a single Algerian artist, Soolking, entered the panel on the strength of one track charting on France's Top 200 and nowhere else, taking the country count to five for the first time since 27 September.","unit":"mixed","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
