“Como La Flor” (like the flower) is the song most people think of when they hear Selena's name. The man she loves is leaving her for someone else. Their love was like a flower he gave her, and now it has withered. She's heartbroken — the famous cry of “¡ay, cómo me duele!” (oh, how it hurts!) — but she wishes him happiness.
It was released in 1992 by Selena y Los Dinos and became her signature, closing almost every concert. It's a cumbia, so even the heartbreak dances.
The image of the wilting flower carries the whole song, and the chorus is slow and clear. Great vocabulary for feelings and for the verb “doler” (to hurt), which works like “gustar”: me duele, it hurts me.
