Multiple songs sit in a tight race for the #2 Spotify weekly position heading into the September 18 chart lock, with several contenders each carrying roughly 50% implied probability. Streaming velocity, playlist momentum, and last-minute promotional pushes from artists like Tame Impala, Malcolm Todd, KAROL G, and Miley Cyrus create the primary competitive dynamics, while legacy tracks from Justin Bieber and Katy Perry trail at lower odds. Recent chart updates and cross-platform engagement metrics will likely serve as the final swing factors before resolution, underscoring how quickly daily streaming data can shift consensus in a crowded field.
