Rajado comes from the verb rajar, which literally means "to crack" or "to split". However, in a colloquial context, especially in Latin American Spanish, rajarse means "to back down", "to give up", or "to chicken out".
In this song, Yeison Jiménez sings, "Pero nunca me he rajado" (But I have never given up/backed down). He uses this powerful word to express his resilience and determination, highlighting that despite suffering and humiliation, he has always persevered. It's a strong, idiomatic expression that conveys a sense of unwavering spirit.
Yeison Jiménez introduces himself in "Así Soy Yo" (That's How I Am) as a proud man from Manzanares, Colombia, with music in his blood. He shares that he's faced tough times, crying and being humiliated, but he's never given up: "Pero nunca me he rajado" (But I've never backed down). He's adaptable, especially when in love, saying "Tampoco me importa el modo, si me toca me acomodo cuando estoy enamorado" (I don't care how, if it's my turn, I'll adapt when I'm in love).
This song is all about owning who he is, no matter what others say: "Y no me importa lo que digan de mí" (And I don't care what they say about me). He's a respectful artist who celebrates his colleagues' success and genuinely appreciates his fans. He also opens up about past loves and heartbreaks that he'll never forget, finding comfort and gratitude in his faith: "Tan solo mi Dios conmigo, siempre ha sido un gran amigo, le agradezco con el alma" (Only my God with me, has always been a great friend, I thank him with all my soul). It's a really honest look at his life and values, reminding us that in life, you win some and you lose some.
