Final answer:
Brenda Lee's 'Rockin' Around The Christmas Tree' hit number 1 on the Billboard Hot 100 in 2023 due to the holiday season's influence on music charts, its discovery by new generations, and Billboard's updated methodology including streaming and digital sales.
Step-by-step explanation:
Brenda Lee's signature Christmas song 'Rockin' Around The Christmas Tree' finally landed at number 1 in the Billboard Hot 100 this 2023, 65 years after its release. There are a few reasons that can help explain this remarkable achievement. First, the holiday season often sees a resurgence of classic Christmas songs on the charts due to increased streaming and radio play. As new generations discover these timeless tracks, their popularity can surge. Secondly, in recent years, there has been a trend where older songs gain renewed popularity through social media platforms, commercials, or movies, essentially giving them a second life. Finally, Billboard's changing methodology, which now includes streaming and digital sales, can significantly impact the chart positions of older songs during the holiday season.
