Envolviste comes from the verb envolver, which literally means 'to wrap' or 'to envelop'.
In this heartbreaking song, Selena sings about how a deceitful lover wrapped her up in a beautiful illusion ("Me envolviste dentro de aquella linda ilusión"). She uses this word metaphorically to describe being completely surrounded and captivated by false promises, making it a vivid and poetic way to express a romantic betrayal.
Have you ever been promised the world, only to have it all disappear? That's exactly what Selena is singing about in "Cobarde." She lays out all the beautiful things her lover told her: that he'd come back soon, that he'd forget his ex, and that he wanted to be hers. He even said, "Que era yo la medicina para tu dolor" (That I was the medicine for your pain). She believed every word and gave her heart to him completely, "sin ninguna condición" (without any condition).
But now, time has passed, and he's nowhere to be found. He's forgotten her. Instead of just being sad, she's calling him out directly. "Cobarde, tú no eres más que un cobarde" (Coward, you are nothing more than a coward). She says he doesn't have the courage to even speak to her and is just running away. The song ends with a powerful warning: sooner or later, "Te vas a acordar bien de mí" (You are going to remember me well).
Selena Quintanilla-Pérez grew up in Lake Jackson, Texas, fronting her family's band, Selena y Los Dinos, with her brother A.B. writing the songs and playing bass and her sister Suzette on drums. She was raised speaking English, and her father drilled the Spanish lyrics into her phonetically, line by line, years before she was fluent in the language she sold millions of records in.
Tejano was a men's business when she took it over: she won the Tejano Music Award for Female Vocalist of the Year nine years running from 1987, and Selena Live! took the 1994 Grammy for Best Mexican-American Album. "Como la Flor", from 1992's Entre a Mi Mundo, is the song attached to her name more than any other, and Amor Prohibido (1994) put four singles at number one on Billboard's Hot Latin Songs chart, among them "Bidi Bidi Bom Bom" and "No Me Queda Más". She was shot and killed in Corpus Christi on March 31, 1995, aged 23, by the former president of her fan club. Dreaming of You, the English-language crossover album she had been recording, was released that August and entered the Billboard 200 at number one.
