context_page_description: Adult Contemporary is a chart published by Billboard ranking the top-performing songs in the United States in the adult contemporary music genre. In 2006, 9 different songs topped the chart in 52 issues of the magazine, based on weekly airplay data from radio stations compiled by Nielsen Broadcast Data Systems.
  In the first issue of Billboard of the new year, the number one song was "Up on the Housetop" by Kimberley Locke, which was in its fourth week atop the chart. Canadian singer Daniel Powter's song "Bad Day" had the longest unbroken run of the year at number one, spending consecutive 18 weeks atop the chart, and also had the highest total number of weeks in the top spot, with 19 non-consecutive weeks in the peak position. The song had been a major hit in Europe in 2005, but did not achieve success in the United States until the following year, after its use in the fifth season of the TV talent show American Idol to accompany video packages spotlighting each eliminated contestant.
