Stella Lefty’s breakout country single “Boston” drives current trader sentiment for the Billboard Hot 100 #2 slot the week of August 29, holding the highest implied probability among named contenders at 45.5% thanks to its steady climb into the top 10 with strong streaming and airplay gains. Multiple major releases create tight competition, including Ariana Grande’s “hate that i made you love me” from her Petal album, Taylor Swift’s Toy Story 5 soundtrack track “I Knew It, I Knew You,” Morgan Wallen’s “Been By Now,” and Olivia Rodrigo’s “Drop Dead,” each backed by established fanbases but showing softer recent trajectories. Ella Langley’s country cuts “Be Her” and “Choosin’ Texas” add further pressure through genre crossover potential. Final streaming and sales data ahead of chart lock-in remain the key swing factors in this crowded field.
