Which 2003 song made Las Ketchup an international one-hit wonder?

“The Ketchup Song (Aserejé)” made Las Ketchup an international one-hit wonder.

Released in 2002 and widely successful in 2003, the song topped charts in numerous countries. Las Ketchup were Spanish sisters whose recording combined Spanish lyrics with a highly memorable dance routine and a chorus based partly on phonetic imitation.

The song’s central character, Diego, tries to sing “Rapper’s Delight” by the Sugarhill Gang. Because he does not know the English lyrics, his version becomes the playful series of syllables heard in the refrain. That explains why the chorus sounds like an invented language rather than standard Spanish.

The title “Aserejé” is derived from that phonetic vocalization. The song was a major international hit, but Las Ketchup did not repeat its worldwide impact with later releases. It is therefore commonly grouped with international one-hit wonders, even though the group continued recording and performing after its peak.
