“Objection (Tango)” is a song by Colombian singer-songwriter Shakira for her fifth studio album and first English-language album Laundry Service (2001). It was the first song Shakira wrote in English after being encouraged by American singer Gloria Estefan to record material in the language. She also produced the track along with Lester Mendez. “Objection (Tango)” musically combines elements of pop rock and tango, and contains instrumentation from the bandoneón and guitar. Through the lyrics of the song, Shakira aims to end a love triangle she is a part of. The song was released as the fourth single from the album on 24 May 2002. A Spanish version of the song, entitled “Te Aviso, Te Anuncio (Tango)” (“I’m Warning You, I’m Telling You”), was also recorded.
Upon its release, “Objection (Tango)” received generally favourable reviews from music critics, some of whom found it similar to the work of American new wave band The B-52’s. Commercially, “Objection (Tango)” was a success and peaked inside the top ten of record charts of various countries such as Australia, Belgium, Italy, Netherlands and France. The song became the last single from the album to chart in the United Kingdom and on the Billboard Hot 100 chart in the United States, reaching numbers 17 and 55, respectively. “Te Aviso, Te Anuncio (Tango)” charted inside the top ten of the US Billboard Latin Pop Airplay and Latin Tropical/Salsa Airplay charts. “Objection (Tango)” was certified platinum and gold in Australia and France by the Australian Recording Industry Association (ARIA) and Syndicat National de l’Édition Phonographique (SNEP), respectively.
An accompanying music video for “Objection (Tango)” was directed by Dave Meyers and features Shakira fighting her unfaithful lover and his mistress in a club. A segment of the video is rendered in an animated cartoon-form. For additional promotion, Shakira performed a samba-inspired version of the song at the 2002 MTV Video Music Awards. It was also included in the setlist of the Tour of the Mongoose, which was launched to promote Laundry Service. “Objection (Tango)” was also used in a Pepsi commercial featuring Shakira.
