This dataset exists to carry cross-column ratios (one column's panel total divided by a different column's panel total), which a single-column sum or share cannot back. The title-only row and the upper-bound row together state how much of the headline could be an artist-credit matching artefact: the difference between the window-wide never-charting count and the same count computed ignoring the artist string entirely.","unit":"count","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
