RBD (formed by Anahí, Dulce María, Maite Perroni, Alfonso Herrera, Christopher von Uckermann, and Christian Chávez) released their second studio album Nuestro Amor in September 2005, to great success.

The band recorded the song in Portuguese, under the name "Esse Coração", as part of Nosso Amor Rebelde, the Brazilian version of their second album.

"Este Corazón" is a Latin pop, soft rock, and sentimental ballad that lasts three minutes and twenty-nine seconds.

It was composed by Armando Ávila who also produced the track alongside Pedro Damián, and is written from the point of view of the group's characters in the telenovela.

The chorus features all the members, with Maite and Christopher singing the lead vocals and Dulce doing double voice with two different tones.

On February 14, 2006, the show's producers surprised the audience with the premiere of the opening video featuring the band performing the song.
