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 and digital sales, and airplay.
In 2006, 20 acts achieved their first U.S. number-one single, either as a lead artist or featured guest, including D4L, Paul Wall, Ali & Gipp, Slim Thug, James Blunt, Ne-Yo, Daniel Powter, Rihanna, Chamillionaire, Shakira, Wyclef Jean, Taylor Hicks, Nelly Furtado, Timbaland, Fergie, T.I., and Akon.
Knowles' "Check on It" and pop singer Daniel Powter's "Bad Day" both topped the chart for five weeks.
[8] "Hips Don't Lie" gave Shakira a number-one single credit, her first since she began her recording career in 1996.
