| - | '''Alternative Songs''' (formerly '''Modern Rock Tracks''' and '''Hot Modern Rock Tracks''') is a music chart in the [[United States]] that has appeared in [[Billboard magazine|''Billboard'' magazine]] since September 10, 1988. It lists the 40 most-played songs on [[modern rock]] radio stations, most of which are [[alternative rock]] songs. The chart was introduced as a companion to the [[Mainstream Rock Tracks]] chart and its creation was prompted by the explosion of alternative music on American radio in the late 1980s. | + | Using a patented digital pattern recognition technology, Nielsen BDS captures in excess of 100 million song detections annually on more than 1,600 radio stations in over 140 [[United States|U.S. markets]] (including [[Puerto Rico]]) and 30 [[Canada|Canadian markets]]. Nielsen BDS also uses the service to track monitored airplay at satellite radio ([[Sirius XM Radio|Sirius XM]]), internet services (like [[Yahoo!]] and [[AOL]]) and audio networks (like [[Dial Global]], [[Music Choice]] and [[Radio Disney]]), as well as on TV (12 U.S. [[music video]] channels and 9 Canadian video channels). |
| - | The chart is based solely on radio airplay and is a component chart of the [[Billboard Hot 100|Hot 100]]. As of 2008, approximately 80 radio stations are electronically monitored 24 hours a day, seven days a week by [[Nielsen Broadcast Data Systems]]. Songs are ranked by a calculation of the total number of spins per week with its "audience impression", which is based upon exact times of airplay and each station's [[Arbitron]] listener data. | + | Since its [[1992 in music|1992]] debut, BDS has become the standard for the radio and music industry because of its accuracy of detecting, tracking and monitoring songs, thus eliminating the use of reporting and call-outs to trades and record labels when it comes to adding and testing tracks. The method has also helped tracks that only received airplay (songs that are not released as singles) become major hits, especially in ''Billboard'''s Hot 100 chart, where several radio-only tracks have reached the top spot. |
| - | Many rock artists do not release commercial [[single (music)|singles]] in the U.S. Several popular songs which were not released as commercial singles did not qualify for the Hot 100 before December 1998, but performed very well on Modern Rock Tracks. | + | ==See also== |
