Sacrificar means "to sacrifice." It's a strong and evocative verb that suggests a significant offering or giving something up for a greater purpose.
In the context of the song, the line "Hay que sacrificar" (One must sacrifice) implies that achieving something desired, perhaps peace or a deeper understanding, requires giving up something else. This word adds a layer of depth and consequence to the lyrics, making it quite memorable.
La Vela Puerca's "Si Fuera por Mí" is a really interesting song about feeling a bit lost and maybe even a little defiant. The singer talks about losing things, like a "me rojas que no me puse en tu pelo" [red thing I didn't put in your hair] and leaving it "en alguna parte entre tanta confesión" [somewhere among so much confession]. It feels like a reflection on past mistakes or missed opportunities, but with a sense of moving on.
There's a cool line where they say, "no me costó más que un par de días el tercero me canso" [it didn't cost me more than a couple of days, on the third I got tired], suggesting a quick recovery from something difficult. And then, "igual vendí la primera mentira que el minuto se compró" [I still sold the first lie that the minute bought], which is a blunt and almost funny way to say they're not perfect. The song seems to be about letting go, saying "no pido más y me voy me sobra solo medicare a molestar" [I don't ask for more and I'm leaving, I'm just bothering you]. It's a song about accepting things as they are and perhaps finding a bit of peace in that acceptance, even if it means just "quedarme solo a molestar" [staying just to bother].
