This is Herencia de Patrones in full flex mode, and they open by telling you exactly that: "We back at it again" and "En lo mismo" (on the same thing). The whole track is a victory lap about staying true to yourself while everybody else copies. They brag that "no son ganchos en lo que canto" (there are no hooks in what I sing), so if you want to hear it again, "repitan la canción" (replay the song). It is a cheeky line and kind of funny.
Money, clothes and swagger
A lot of the song is pure corrido-trap bragging. "Balenciaga zapatos parecen calcetines" (Balenciaga shoes look like socks) is a real image of those sock-style sneakers, and "No puedo pronunciar la mitad de la ropa que tengo" (I can't pronounce half the clothes I own) is a great joke about designer labels like MCM and Dolce. There is also a rougher side: the Glock in the pocket and the .57 are about feeling protected on the street, and this is not a song for kids.
Slang worth knowing
The attitude is clear: "¿Qué sabes de originalidad si te la pasas haciendo lo que hacen otros?" (What do you know about originality if you spend your time doing what others do?). They are calling out imitators, and they sound like they are having a lot of fun doing it.
