Mainstream rock

Mainstream rock (sometimes called heritage rock) is a radio format used by many commercial radio stations in the United States and Canada.

Format background

Mainstream rock stations are between classic rock and active rock on the programming spectrum, in that they play more classic rock than active rock stations, but play more modern rock than classic rock stations. In many ways, mainstream rock is a successor to the widespread album-oriented rock (AOR) format created in the 1970s.

As of 2011^[update], some examples of mainstream rock stations in terrestrial radio include: KEGL/Dallas, TX , KRXQ/Sacramento, CA, WEBN/Cincinnati, OH, WMMS/Cleveland, OH, KISS/San Antonio, TX, KSHE/St. Louis, MO, KLBJ/Austin, TX, KDKB/Phoenix, AZ, KBER/Salt Lake City, UT, WDVE/Pittsburgh, PA, WFYV/Jacksonville, FL, WAPL/Appleton, WI, KZRR/Albuquerque, NM, KEZO/Omaha, NE, WHJY/Providence, RI, KTUX/Shreveport, LA, KSQY/Rapid City, SD, and KZOZ/San Luis Obispo, CA. Most have a very long heritage that dates back to the 1970s as AOR stations, which is why several trades like Billboard and R&R will refer these stations as "Heritage Rock".

Rock Airplay chart

The Rock Airplay chart is a chart that compiles the current hits on rock radio stations and is reflected as a component in Billboard's Mainstream Rock Tracks chart. The Rock Airplay chart is exclusive to R&R, with thirty positions on this chart and it is solely based on radio airplay. Twenty-four rock 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.

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 20 and have been on the chart after 26 weeks are removed and go to recurrent status.
