The Tropical Airplay chart (formerly known as Tropical/Salsa and Tropical Songs) is a record chart published by Billboard magazine introduced in 1994. The first number-one song on the chart was "Quien Eres Tu" by Luis Enrique. Originally, rankings on the chart were determined by the amount of airplay a song received on radio stations that primarily played tropical music, namely music originating from the Spanish-speaking areas of the Caribbean such as salsa, merengue, bachata, cumbia, vallenato, and tropical fusions. Any song, regardless of its genre, was eligible for the chart if it received enough airplay from the panel of tropical music radio stations being monitored.
