**BbY WOW** by KAROL G, Judeline, and rusowsky holds overwhelming market-implied odds as the likely #1 Spotify song for the week of September 25 due to its sustained dominance on global streaming charts. The track, released August 7 from Karol G’s album *No Me Arrepiento de Sentir Tanto*, has posted multiple weeks at No. 1 on the Billboard Global 200 and Spotify Global with weekly streams exceeding 42 million, driven by strong Latin-market performance and a danceable Coolie Dance Riddim sample that fueled viral momentum. Its consistent top rankings across regions, including repeated No. 1 peaks in Mexico, Colombia, and Spain, reflect broad listener engagement and promotional tailwinds. An upset would require a major new release or unexpected surge from competitors like Malcolm Todd’s “Earrings” or catalog tracks to overtake its current trajectory before the weekly chart locks.
