Hot Dance Airplay

From Wikipedia, the free encyclopedia

Hot Dance Airplay is a monitored dance music radio chart that is featured weekly in both Billboard magazine and its sister publication R&R (online only). The chart came about as a result of the small but influential impact of dance music on the radio in the United States and the stations that program it. The chart made its debut on October 17, 2003 with "Just The Way You Are" by Milky being the first number one song. The current number-one for the issue dated December 8, 2006 is "My Love" by Justin Timberlake featuring T.I..

[edit] Chart criteria

There are twenty-five positions on this chart. They are ranked by the number of detections (calculated by summarizing a song's number of spins and the audience size of the radio station playing it). Songs receiving the greatest growth will receive a "bullet", although there are tracks that will also get bullets if the loss in detections doesn't exceed the percentage of downtime from a monitored station. "Airpower" awards are issued to songs that appear on the top 20 of both the airplay and audience chart for the first time, while the "greatest gainer" award is given to song with the largest increase in detections. A song with six or more spins in its first week is awarded an "airplay add". If a song is tied for the most spins in the same week, the one with the biggest increase that previous week will rank higher, but if both songs show the same amount of spins regardless of detection the song that is being played at more stations is ranked higher. Songs that fall below the top 15 and have been on the chart after 26 weeks are removed and go to recurrent status.
