Secret Affair
Charting Aug 25, 1979 → Oct 31, 1981 · 34 weeks with chart power
Charted in 1 of 2 markets — UK Singles Chart 34 wk
Billboard Hot 100 and UK Singles Chart combined, weighted · UK Singles Chart data ends Sep 18, 2026 · 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 Chart ×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.
UK Singles Chart data runs to Sep 18, 2026; later weeks combine the Billboard Hot 100 only, so their shares — and the most recent years' Era Power — are lower than a full week's would be.

Songs on the Global Music Power
5 records · 11 share-weeks of Career Power
Power contributed is what each song earned this artist: their weekly Power Share, split across their songs (a featured credit takes its reduced share). Record Power is the song's own figure, the same for every artist on it. Bar length compares songs within this list. On this combined chart each song's figures are its figures on each market, weighted as the chart weights them, so the list still adds up to Career Power; peaks and weeks are shown per market.
