Musically, the song is often performed with the instrumentation of a ranchera or a bolero, styles that rely heavily on the interplay between the voice and traditional strings or mariachi horns. This musical backdrop serves to amplify the lyrical content. When Gabriel sings, "Me voy sintiendo morir" (I go feeling like I’m dying), the music swells to meet her anguish. Yet, the melody remains stately and measured. There is no histrionics or begging; there is only the raw statement of pain. The juxtaposition of the dying heart mentioned in the lyrics against the steady, marching rhythm of the music suggests a person who is crumbling inside but walking away with their head held high.
[Coro] Pero ahora dices que te arrepentiste Que extrañas mis besos, que quieres volver Y es tarde, ya es tarde, no juegues conmigo Tú mismo cerraste la puerta al querer
Tú Lo Decidiste stands out because it’s the only one where the singer completely rejects reconciliation — not out of spite, but out of self-preservation.
[Bridge] I don't want your pity, nor your compassion I don't want you to come back out of need Find another love, because mine is gone You decided it, I only accepted
Furthermore, the song acts as a mirror to the partner's character. By deciding to leave, the partner has revealed their true nature. The lyrics imply a sense of relief amidst the sorrow—a recognition that a love that can be walked away from so easily was perhaps not as solid as believed. There is a subtle rebuke in the way Gabriel delivers the lines; she is not pleading for return, but rather documenting the exit. This transforms the song from a "breakup song" into a "moving on song." It captures that specific moment in a relationship's timeline where the grief peaks, but the healing begins.
