Billboard Dance Airplay mechanics — weighted radio spins drive chart trajectories
| Station |
|---|
Weekly chart points = Σ (station spins × market weight). Stations: KIIS/Z100 (1.0), B96 (0.9), KHKS/WIOQ (0.8), KUBE/KMVQ (0.7), WXKS/KZZP (0.6), KHTS/WLLD/KQKS (0.5). Rank determined by weekly points against simulated chart panel thresholds. This models audience-weighted impressions, not raw spin counts.
