Barisia is a less common, older form of the word avaricia, which means 'greed' or 'avarice'. It's an interesting choice because it's not a word you hear every day in modern Spanish, making it stand out.
In the song, the singer admits, "Pero mis ojos sonre pasan la barisia" (But my eyes only see greed). He uses this word to confess his weakness for other women, acknowledging that his gaze is drawn by a kind of 'greed' or desire that leads him astray from his partner. This makes it a key word for understanding his regret and the song's central theme of infidelity and repentance.
Ulices Chaidez's "No Cabe Duda" is a really honest look at a guy who messed up big time in a relationship. He starts right off by saying, "Necesito decirte, que te adoro" [I need to tell you, that I adore you], and he's full of regret for hurting her. He admits he was unfaithful and calls himself "un idiota" [an idiot] for losing her. It's clear he's struggling with the difference between love and temptation, saying, "No cabe duda que el amor es una cosa Y la tentación es otra soy muy débil ya lo se" [There's no doubt that love is one thing And temptation is another, I'm very weak, I know it].
He's pretty blunt about his weaknesses, even confessing, "Mi mente tiene malicia yo no soy solo de ti" [My mind has malice, I'm not only yours]. It's a song about acknowledging your flaws and the pain you've caused, even if you know you might not be able to change completely. He recognizes that his heart can deceive him and that he's like "todos al de una bella mujer" [everyone when it comes to a beautiful woman]. It's a raw and relatable confession from someone who knows they messed up but can't seem to escape their own nature.
