"En éxtasis" produced seven hit singles, received several certifications and consolidated her career. The lead single "Piel Morena" was a hit in the Latin market, while the single "Maria la del Barrio" was very popular, thanks to the soap opera of the same name. The album was nominated for Pop Album of the Year at the Lo Nuestro Awards of 1996.
"En Éxtasis" was produced by the Mexican producer Oscar López, except for the songs "Piel Morena" and "Me Faltas Tú", which were produced by Emilio Estefan and Kike Santander.
The album includes several cover songs:
In Argentina, "Gracias a Dios" was the soundtrack of the soap-opera "María la del Barrio" ("Mary from the block"), starring Thalía, instead of the song with which it was originally released in México (and which also became a hit).
The number of songs included in "En Éxtasis" was not the same in all the countries where it was released. This is due to the fact that, at the same time the album was being released, Thalía's most successful soap-opera, "María, la del Barrio" ("Mary from the Block"), was being broadcast in all Latin America . Even though this contributed to expand Thalía's popularity throughout the Continent, it also made different people enjoy different songs. For example, the Brazilian version of the album features, as bonus tracks, a remixed version of the songs "Amándote" ("Loving you") and "Gracias a Dios" ("Thanks to God"), and the soundtrack from "María la del Barrio" ("Mary from the block"). However, this version does not include the song "Juana". On the other hand, the Argentinean version of the album features, as a bonus track, only a remixed version of "Piel Morena".
