Taylor Swift’s surprise drop of “Patient Zero” as the lead track on the expanded *The Life of a Showgirl: The Encore* edition on September 25 has fueled explosive early streaming momentum. The glossy pop single, written with Max Martin and Shellback, immediately set a 2026 Spotify record for the most-streamed song by a female artist in a single day and placed the four new tracks in the global Top 4. This builds on the original album’s historic first-week performance and benefits from sustained Swiftie engagement plus the high-profile music-video premiere at the MTV VMAs on September 27. Traders are tracking how these factors, combined with ongoing playlist adds and promotional lift, shape cumulative first-week stream totals ahead of chart lock.
