Infierno literally means "hell." While it's a very strong word, it's often used in Spanish songs and poetry as a powerful metaphor for emotional suffering.
In this song, Enrique Iglesias expresses his desperation by asking how he can "escaparme de este infierno" (escape from this hell). This dramatic use of the word vividly paints a picture of his torment and longing, making it a very memorable line.
Have you ever been so completely in love with someone that you can't even say the words? That's the whole story of this song. Enrique Iglesias is totally obsessed with someone, telling us, "No hay un minuto al día que no piense en ti" (There isn't a minute of the day I don't think about you). He has "tres palabras" (three words) he's desperate to say, but every time he gets close, the words "se pierden al mirarte" (get lost when I look at you).
This feeling is so intense he calls it an "infierno" (hell) that he needs to escape. His heart "no quiere callar" (doesn't want to be quiet) because he feels that love can be fleeting, that it "llega de pronto y huye sin decir adiós" (arrives suddenly and flees without saying goodbye). He decides he won't let the chance slip away, promising to follow this person until he finds them and finally says the words he's never said before.
Enrique Iglesias shopped his first demos around Madrid under the name Enrique Martínez, so that no label would sign him for being Julio Iglesias's son. Fonovisa signed him anyway and flew him to Toronto, where he recorded Enrique Iglesias (1995) in near anonymity. All five of its singles, "Si Tú Te Vas" and "Experiencia Religiosa" among them, reached number one on Billboard's Latin chart, and the album won the 1997 Grammy for Best Latin Pop Album.
Enrique (1999) moved him onto English-language radio, with "Bailamos" and "Be with You" both topping the Hot 100, and Escape (2001) sold past eight million copies on the back of "Hero". The chart he owns outright is Hot Latin Songs: 27 number ones, more than any other artist, plus the two longest runs at the top in its history, "Bailando" with Descemer Bueno and Gente de Zona at 41 weeks in 2014 and "El Perdón" with Nicky Jam at 30 weeks in 2015. He wound the recording career down on his own terms, calling Final (Vol. 1) in 2021 and Final (Vol. 2) in 2024 his last albums.
