Alevosía translates to "treachery" or "perfidy". It's a strong and somewhat formal word, often used in legal contexts to describe an act committed with premeditation and malice, taking advantage of someone's defenselessness.
In the song, the lyric "me di cuenta que no se que fue con alevosía" suggests a realization that an action was carried out with deliberate deceit or betrayal, highlighting the deep sense of hurt and betrayal central to the theme of "Falsa Amistad" (False Friendship).
This song, "Falsa Amistad" (False Friendship), is a really intense look at the destructive power of addiction and the betrayal that can come with it. The lyrics paint a vivid picture of someone who has lost everything, feeling their body on the ground and regretting their foolish choices: "ha amanecido mi cuerpo está en el suelo, no hay que haber vencido todo lo que he perdido por ser un estúpido" (dawn has broken, my body is on the ground, I didn't have to win everything I've lost for being stupid).
The song talks about how easy it is to fall into a trap, selling your soul "por medio gramo" (for half a gram) and how there's "no hubo marcha atrás" (no turning back). It's a stark warning about the path of addiction, showing how it destroys lives and relationships, even with family. The lyrics also touch on the hypocrisy of those who pretend to be friends but are only around for their own convenience, highlighting the pain of realizing that "pura conveniencia era sumar su amistad" (pure convenience was adding their friendship).
