"Emociones" (Emotions) is La Santa Grifa at his darkest. The song opens cold, literally: "El frío me cala en los huesos" (the cold chills me to the bone), and from there he talks with his own subconscious, which wants him to "volarse los sesos" (blow his brains out). Heavy stuff, and he does not soften it: his heart is "repleto de grietas" (full of cracks) and the demons inside him are laughing.
The chorus is the heart of it and easy to learn: "Pienso que todo es una ilusión, que estoy muerto desde aquella ocasión" (I think everything is an illusion, that I've been dead since that one time). He feels "atrapado en esa estación" (trapped at that station), with his emotions "en una prisión" (in a prison). In the verses he numbs it all with partying, a girl he won't commit to ("soy mujeriego", I'm a womanizer) and weed, "me automediqué" (I self-medicated), with an angel on one shoulder and a demon saying "drógate más" (get high some more). It is bleak and honest, a song about depression rather than a party track, so take it seriously.
