Ilusorias translates to "illusory," meaning based on illusion and not real. It's a less common word that adds a philosophical depth to the lyrics.
In the song, Guaynaa sings, "Todas, esas líneas son ilusorias" (All those lines are illusory). He uses this word to suggest that the divisions and boundaries we perceive in life are not as real or permanent as they seem, emphasizing the interconnectedness of humanity.
Guaynaa and Cabra's "Somos" is a really thoughtful song that makes you think about humanity as a whole. They talk about how "La gente viene y se va" [People come and go], and how we're all caught "Jugando entre el bien y el mal" [Playing between good and evil], experiencing "Amor y miedo" [Love and fear]. It's about the universal human experience of living on the same planet, feeling connected to "la tierra y el mar" [the earth and the sea], and always "Buscando tiempo para los sueños" [Looking for time for dreams].
What's cool is how they acknowledge the ups and downs: "Se lastimarán y luego se van a sanar" [They will get hurt and then they will heal]. It's a cycle, where "Llega el final, después todo vuelve a empezar" [The end comes, then everything starts again] under the same sky. The chorus really brings it home, reminding us that "Somos, siete mil millones de historias" [We are, seven billion stories], all of us wanting to "terminar en la gloria" [end in glory]. They even get a bit scientific, mentioning how our hearts produce a magnetic field, connecting us all as "un entero y una memoria" [a whole and a memory]. It's a big picture view of life, and it's pretty profound!
