In the song "Al vacío" by Pedropiedra, the lyrics explore various existential questions about the universe and our place in it. The first verse asks how many liters of water are in the sea, and how many kilograms of salt exist. These seemingly simple questions touch upon the vastness and complexity of the world we live in. The next few lines talk about the stars and how they course through our veins, connecting us all together. The lines "Me contienen a mi / Corro pos sus venas igual / De principio hasta el final" suggest that we are all connected in some way, and that we are all running the same course from birth to death.

The chorus repeats the phrase "Cuando caigo al vacío" which translates to "When I fall into the void." This line suggests a sense of falling or losing control, yet the next line "Floto en el aire un rato" means "I float in the air for a while" implying a sense of freedom or weightlessness. The next line "Aterrizo con la destreza de un gato" means "I land with the skill of a cat" implying that this falling sensation is not necessarily a negative experience, but rather a challenging one that can be overcome with grace and agility. However, the last line of the chorus, "Pero siempre hay algun perro esperando / Morderme, comerme" meaning "But there's always a dog waiting / To bite me, eat me" reminds us that life can be unpredictable and there will always be unexpected obstacles on our path.

Overall, the song reflects on the wonder and uncertainty of life, while encouraging listeners to find strength and resilience in the face of adversity.
