El Cisne (The Swan) is Camilo's song about finally feeling like you belong. It opens with someone who was ready to quit: "Estuve a punto de tirar la toalla" (I was about to throw in the towel), the same boxing idiom we use in English. He was "prendiendo velas en un mundo oscuro" (lighting candles in a dark world) and living in a house full of windows where he only saw walls.
The second verse is the honest part. He dressed up as someone else so many times that "un día me vi y no me reconocí" (one day I saw myself and didn't recognise me), and he said sí when he wanted to say no. He always saw the world in colour but pretended it was grey, all to make other people happy. Then someone calls to him from far away, "Vente" (come here), and the chorus lands on its best line: "no es dónde, sino quién te abraza" (it's not where, but who hugs you). Home is a person.
Learner tip: "dar la talla" means to measure up or be good enough, and "ir contracorriente" is going against the current. The title never appears in the lyrics, but a swan is the ugly duckling grown up, which fits a song about finally being yourself.
