Global chart leaps like Sienna Spiro's ‘Great Expectation’ jumping +14 spots to #24 with 2.4M streams represent critical viral inflection points. Chart positions on Spotify Global follow a strict power-law distribution:

• Top 10 Threshold: Typically requires between 3.7M and 4.2M daily streams depending on holiday seasons and competing blockbuster album drops.
• #1 Global Threshold: Ranges from 5.5M to 9.5M+ streams depending on global megahit velocity.
• Decay & Plateau Dynamics: Breakout records undergo a logistic acceleration followed by exponential decay toward a recurring catalog baseline (usually 15–25% of peak streaming velocity).
