Costal translates to "sack" or "large bag". While seemingly simple, its use in this song's title, "El Costal Lleno De Piedras" (The Sack Full of Stones), is quite evocative and not an everyday word in song lyrics.
In the context of the song, a "costal lleno de piedras" likely symbolizes a heavy burden, difficulties, or emotional weight that someone carries. It's a powerful metaphor that hints at struggle and resilience, making it an interesting and memorable word choice.
This song by Los Alameños De La Sierra is a really interesting look at how people change when they get money. The singer talks about how he's still the same person, even though he now has "dinero" [money] and "acero" [steel, perhaps symbolizing wealth or power]. He says his "escuela de cero" [school of zero] means he came from nothing, and that keeps him grounded. It's a blunt reminder that true value comes from who you are, not what you have.
He also talks about people who only come around when things are good, saying he doesn't want them near him "tras que las malas que fueron" [after how bad they were]. He's learned to stand up for himself, declaring "ya se me acabó es el miedo" [that fear is over for me]. The image of the "costal lleno de piedras" [sack full of stones] is really powerful, suggesting he's carrying the weight of past experiences or perhaps the burdens of his new success. It's a song about staying true to yourself and recognizing who your real friends are, even when your circumstances change dramatically.
