Karol G’s “BbY WOW” with Judeline and rusowsky holds overwhelming trader consensus as the likely #1 Spotify global song for the October 9 chart week because of its sustained dominance and streaming resilience. The track logged multiple consecutive weeks at No. 1 on Spotify’s daily and weekly global tallies through September into early October, fueled by massive Latin American and Spanish-language engagement plus a viral dancehall riddim sample that boosted club and playlist traction. It also topped Billboard’s Global 200 for several frames with over 39 million weekly streams at peaks, outpacing newer entries from ADÉLA and Malcolm Todd. Fresh Taylor Swift debuts could narrow the gap on the next update, yet the song’s established audience and regional stronghold make a clear upset unlikely absent a massive coordinated push from competitors.
