BbY WOW by KAROL G, Judeline, and rusowsky holds the market's clearest edge at 58% implied probability for the #2 Spotify song the week of October 2, driven by recent streaming traction and Latin-music crossover appeal. The field remains tightly contested, with multiple unnamed tracks and "Other" each hovering near 50%, reflecting uncertainty over late-week surges from established artists. Lower-probability options like ADÉLA's singles, Malcolm Todd's "Earrings," and Taylor Swift's "Patient Zero" sit at 3% or below, underscoring limited expected momentum. Key swing factors include final streaming data drops, playlist placements, and any surprise promotional pushes before the chart locks.
