Solo career plus "Joan Jett & the Blackhearts": bands billed under the leader's name (credit survey, 2026-09-24).
billboard-hot-100 and uk-singles combined, weighted · How it works
Each week an artist's share is the weighted mean of their Power Share across billboard-hot-100 ×1 and uk-singles ×0.45 (weights ∝ √population, US = 1). The divisor is every chart's weight, so a number one is worth the same share in any era — and a week before every chart exists, or after one's data ends, sums to less than 100.

Exponentially smoothed share of the week's total power (the primary metric). The bold line is the group; the others are each member's weighted contribution.
| Member | Weight | Contributed power | Weeks |
|---|---|---|---|
| Joan Jett | × 1 | 4 | 14 |
| Joan Jett & the Blackhearts | × 1 | 106 | 131 |
Contributed power = weight × the member's own Power Share, summed over weeks. The member's standalone page is unaffected by this grouping.
