Porfías comes from the verb porfiar, which means to insist, persist, or be stubborn, often in a negative or annoying way.
In the song, the line "¿Por qué porfías? Por favor, mejor estáte ausente" translates to "Why do you insist? Please, it's better if you're absent." It's an interesting word because it captures a sense of exasperation with someone's persistent and perhaps unwelcome presence or argument, making it more nuanced than a simple 'you say' or 'you talk'.
Rayden's "Nunca Sera Siempre" is a really thought-provoking song about the fleeting nature of things and the lies we tell ourselves. He starts right off with a blunt truth: "Nunca será siempre" [It will never be forever], and warns us, "Nunca digas nunca, porque siempre se arrepiente" [Never say never, because you always regret it]. He talks about how people "Miente más que habla, bla bla bla, siempre miente" [Lie more than they speak, blah blah blah, always lying], maybe even to themselves.
He gets pretty personal, admitting he was "Siempre fui de frente y nunca fui valiente" [I always went straight ahead and was never brave], perhaps because of the fear of losing someone. There's a sense of regret about past relationships, like when he says, "no supe tenerte" [I didn't know how to have you] and "nunca supe amarte" [I never knew how to love you]. He uses some cool imagery, contrasting "Sábanas frías para un cuerpo de sangre caliente" [Cold sheets for a hot-blooded body]. The song really makes you think about those big, absolute statements we make, especially when he repeats, "Nunca será siempre" [It will never be forever] and mentions saying "Hasta Nunca" [See you never] or "Para Siempre" [Forever]. It's a reminder that nothing is truly permanent.
