Top 100 Brasil, previously Brasil Hot 100 Airplay, is the music singles charts in Brazil, compiled by Crowley Broadcast Analysis. In the beginning, the chart was published monthly by Billboard Brasil since the release of the magazine, in October 2009. Since April 2014, the Brazilian Billboard began publishing on its Brazilian site, the weekly Hot 100, as it is, and has always been held at the site, and Billboard magazine in other countries as well as the American Billboard.
It is the top 100 songs, both national and international titles, the most varied genres, computed based on the total number of executions in the period indicated and the grid base stations Crowley, that monitors 256 radio stations located in the grid-base stations, made from Monday to Friday from 7 am to 7 pm. This grid includes the cities of São Paulo, Rio de Janeiro, Brasília, Campinas, Ribeirão Preto, Belo Horizonte, Curitiba, Porto Alegre, Recife, Salvador, Florianópolis, Fortaleza, Goiânia, Campo Grande, Cuiabá and the Triângulo Mineiro, Vale do Paraíba and Paulista Littoral mesoregions.
In 2018, the company launches the Crowley Charts website, which compiles charts that were released weekly by Billboard Brasil. The site features the Top 100 Brasil, with the 100 most performed songs of the week, and charts with the 10 songs most played by genre (National Pop, International Pop, National Pop/Rock, Pagode, Sertanejo, Forró, Funk/Black Music and Gospel). In January 2019, Billboard Brasil is closed and Crowley Charts becomes the only website to release the weekly chart.
The first song which reached in number-one on the chart was "Halo" by Beyoncé. "I Want to Know What Love Is" by Mariah Carey is the longest running number 1 (27 weeks), followed by Beyoncé's "Halo" (the most played song in the country, in 2009).
