PURO is LOUTA celebrating something clean and unfiltered, and the chorus has fun with it. "Puro y esto es un montón" (pure, and this is a lot) sits next to "Lejos de cualquier dicotomía" (far from any dichotomy), which is a pretty fancy word to drop in a dance track. "Un montón" is everyday Argentine Spanish for "a lot", so it's worth stealing. The best image is "Mientras bailamos como bolsas en el aire" (while we dance like bags in the air), plastic bags floating over "casi todo Buenos Aires" (almost all of Buenos Aires).
The verse gets more thoughtful. "Para decir la verdad no hace falta inventarla" (to tell the truth you don't need to invent it), you just have to "reconocerla en los detalles" (recognise it in the details). Later the lines tumble out fast: looking at himself, looking at you, "no puedo ver mis venas" (I can't see my veins), "me veo en la vereda" (I see myself on the sidewalk; "vereda" is the Argentine word for it). He admits that out of fear of understanding everything, "uno termina esperando lo peor" (you end up expecting the worst). A lovely bit of honesty in the middle of a song that mostly wants you moving.
