Top 40 Hits
Top 40 hits is a music category that is composed of the most popular songs for a specific time period and genre. In the world of radio airplay, the category of top 40 hits is essential because this often dictates the frequency with which radio disc jockeys should play the popular songs included in the top 40 hits. While a lot of radio stations emphasise musical diversity and entertain listeners' song requests, disc jockeys are still obliged to play the top 40 hits because these songs are what the listeners want to hear.
Most radio stations produce their own top 10, top 20 or top 40 hits charts based on song requests and called-in votes for radio surveys. Magazines and other websites, meanwhile, get the data for their top 40 hits charts from album and record sales, as well as digital downloads. This data-gathering process for top 40 hits charts is often controversial, not only because of erroneous data but also for questionable methods used. One of the controversies that music charts faced is the news that some publishers of top 40 hits charts reportedly base their rankings on the number of album copies shipped to retail stores, instead of the actual album sales figures.
