In Depth
Music charts (Billboard Hot 100 in the US, Official Singles Chart in the UK) rank songs by a combination of sales, streaming, and radio airplay. Reaching number one is the ultimate commercial achievement. The chart system shapes the industry by determining radio playlists, marketing budgets, and public perception of success. Chart methodology has evolved from pure sales to streaming-weighted calculations, fundamentally changing what it means to have a hit.
The Beatles hold the record for most number-one singles on the Billboard Hot 100 with 20, a record that has stood since 1970 and may never be broken.
