Puñaladitas is a fascinating and dramatic word. It combines puñalada (a stab or dagger wound) with the diminutive suffix -ita, translating to "little stabs".
In the song, ROSALÍA uses this powerful metaphor to describe the sharp, repeated emotional pains caused by ambition. She sings, "Puñaladitas da su ambición" (Her ambition deals little stabs), vividly illustrating how the pursuit of fame can hurt you deeply, like tiny, sharp wounds to the heart.
In this song, ROSALÍA tells a story about a painful choice she had to make. She starts by saying, "Lo que pasó / A ti te lo cuento" (What happened / I'll tell you), as if she's confiding in a friend. She had a special relationship with someone, her "bebé," but she became obsessed with her career, with "Miles de canciones en mi mente" (Thousands of songs in my mind). Her partner saw this obsession was hurting him and warned her many times, but she admits, "Y yo como si nada" (And I acted like it was nothing).
She personifies fame as a terrible partner, singing, "Es mala amante la fama" (Fame is a bad lover). This lover is treacherous, jealous, and will leave you as quickly as it arrived. ROSALÍA warns that you can have a temporary relationship with fame, but you should never fully commit: "Si quieres duerme con ella / Pero nunca la vayas a casar" (If you want, sleep with her / But never marry her). She knows this obsession is dangerous, describing fame's ambition as giving "Puñaladitas... En el pecho" (Little stabs... in the chest), yet she still feels trapped by it.
