Cobardía translates to "cowardice." It's a strong and evocative word that isn't as common in everyday song lyrics, making it stand out.
In the context of the song, Kany García sings, "Y esta cobardía me quema por dentro" (And this cowardice burns me inside). She uses it to express the intense internal struggle and regret caused by her own fear or hesitation, which prevents her from acting on her feelings. This emotional depth makes the word particularly impactful.
Have you ever felt something so strongly for someone that keeping it a secret feels like it's literally killing you? That's the powerful emotion Kany García and Alejandro Sanz explore in "Muero." The song describes a love that is so intense it's like a fire, or a hoguera, that the speaker is constantly trying to put out. Every laugh and every hug from this person brings both joy and a "bitter pain," because the true feelings can't be expressed.
The lyrics paint a picture of someone who knows everything about the person they love, from their biggest fears (tus grandes miedos) to their dreams for the future. Yet, they are trapped by silence and fear. The chorus repeats the desperate cry, "Que muero / De tanto callar" which means "I'm dying / from keeping so quiet." It's a powerful song about the agony of unspoken love and the burning desire to finally break the silence and say what's in your heart.
