Vociferaban comes from vociferar, meaning to shout, yell, or loudly voice an opinion. It is a vivid and less common word, related to the idea of making a noisy public outcry.
In the song, Santa RM uses it for the people who loudly criticized him but later changed their attitude, giving the word a sharp sense of noisy, hypocritical criticism.
“Alla Afuera” sounds like a reply to everyone waiting for Santa RM and Smoky to fail. The hook says, “Allá afuera me esperan, quieren que yo me muera” [Out there they are waiting for me, they want me to die], then answers, “No pueden con la envidia y lo que les fastidia es que yo sí pudiera” [They cannot handle their envy, and what bothers them is that I was able to do it]. The song places the artists outside, surrounded by critics who inspect their careers and search for mistakes while ignoring their successes. The image is blunt and almost confrontational: people talk about their money and say the lyrics do not justify it, while the artists tell those critics to write more and criticize less.
The verses also show where their confidence comes from. They say nobody bet on them when they started writing, and that nothing was given to them: “Pasión y sentimiento” [Passion and feeling] helped them build their path. Family appears as a source of support, especially in the repeated line about being waited for at three in the morning, although that section is fragmentary in the lyrics. There is also a funny, sharp warning in “Karma acostumbra cobrar con su propio veneno” [Karma usually collects payment with its own poison]. Santa RM and Smoky reject envy, imitation, and accusations that they have “sold out,” insisting that they are responsible for their own work. The mood is proud, defensive, and a little mocking: if people keep talking, the artists will keep moving forward.
