"Yeah!" was the longest-running number one single in 2004, subsequently topping the year-end chart on the Hot 100. It was certified platinum by the Recording Industry Association of America (RIAA). The song received a similar response in other countries, topping fourteen charts worldwide. It was certified platinum in several countries, including Australia, Belgium, Canada, Germany and Norway, and received a two times platinum certification in New Zealand. The song peaked in the top-ten in several Year-end charts.
"Yeah!" was met with universal critical acclaim, with critics lauding its production, more specifically its combination of crunk and R&B. An accompanying music video, directed by Mr. X, shows Usher performing choreography in a club in front of blue laser beams.
