Stella Lefty’s “Boston” commands near-certain trader consensus for the Billboard Hot 100’s #2 spot on the September 5 chart due to its sustained late-summer momentum. The country-pop single has posted steady gains in U.S. streams, radio reach across pop and country formats, and sales, recently climbing into the top five and flirting with a new peak just behind Ella Langley’s long-running “Choosin’ Texas.” Its crossover airplay, fan-driven streaming spikes, and regional radio strength in key markets have created a durable points cushion that competitors have struggled to close. An upset would require an unusually sharp last-minute surge from one of the lower-probability tracks—such as a major streaming spike or promotional push—that outpaces “Boston” in the final tracking days before the chart locks.
