Aserejé (“The ketchup song”)

"The Ketchup Song (Aserejé)" (pronounced [aseɾeˈxe]) is the debut single by Spanish pop group Las Ketchup, taken from their debut studio album Hijas del Tomate (2002). The song is about a young man who enters a nightclub while singing and dancing. In addition to the original Spanish version, the song exists in a form with Spanglish verses, although the nonsensical chorus is identical in both versions.

"The Ketchup Song" was released on 10 June 2002 and became an international hit the same year. It reached number one in at least 20 European countries and became the best-selling hit of 2002 in eight of them. It also topped the music charts of Australia, Canada, and New Zealand but stalled at number 54 in the United States. In Central and South America, the song became a number-one airplay hit. As of 2006, the song had sold over seven million copies worldwide. The song's dance routine was a popular novelty dance in the early 2000s.
