On each of the first five rows that difference equals, to the stream, the export streams of one artist, Ramy Sabry, whose country of origin was unresolved in this desk\u2019s roster until a correction on 15 September 2026 and who could therefore not enter an export population keyed on resolved African origin. From 16 September, the first composition built after that correction, the difference is zero. No other artist accounts for any part of the gap on any of the seven dates. This is a measurement change and not a chart change: Ramy Sabry held a Top 200 position in Saudi Arabia and the United Arab Emirates on all twenty dates the desk holds.","unit":"streams","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
