The
Billboard Hot 100 is a chart that ranks the best-performing
singles of the United States. Published by
Billboard magazine, the data are compiled by
Nielsen SoundScan based collectively on each single's weekly
physical sales and
airplay. In
2004, there were 11 singles that topped the chart. Although there were 12 singles that claimed the top spot in the 52 issues of the chart,
hip hop duo
Outkast's "
Hey Ya!" began its peak position in 2003, and is thus excluded.
