Tapado de visón means “mink coat,” a luxurious fur coat. In the song, the singer imagines descending the stairs in a wig and mink coat as part of a dramatic solo show, making this unusual phrase a vivid and memorable detail.
BAILAR O MORIR is a party for one, and it is a blast. BOM, with Miranda! and Lali along for the ride, opens with a world that is too loud: "Hay tanto ruido afuera" (There is so much noise outside). So she switches off her head, leaves the key in the lock so "Nadie puede pasar" (Nobody can come in), and declares "Esta es mi propia fiesta" (This is my own party). The rule of the house is the title: "Hay que bailar o morir" (You have to dance or die). It is dramatic on purpose, and that is the fun of it.
The guest list? "Soy solamente yo" (It's only me). She dresses up anyway, "Con mi mejor peluca" (With my best wig) and a "Tapado de visón" (mink coat; tapado is the Argentine word for a long coat, where Spain would say abrigo), and makes a grand entrance down the stairs because "Va a comenzar el show" (The show is about to begin). The chorus explains why: when she dances, "Me olvido de todo" (I forget everything), with "la mente en blanco" (my mind blank, a handy idiom for having your head totally empty). Dancing alone in your living room in a wig has never sounded this glamorous.
