Corona literally means "crown". While it's a common word, its use in this song is particularly striking and metaphorical.
In the lyrics, "Acaso dime quién te dio corona / Y quién te dio el derecho ilícito para opinar" (Tell me, who gave you a crown / And who gave you the illicit right to opine), the word "corona" symbolizes authority, power, and the right to judge or dictate. The singer challenges someone who acts as if they have superior status, questioning their self-proclaimed right to criticize or control. This makes it an engaging word that highlights a central theme of defiance and self-expression in the song.
"Arte" is Mau & Ricky's answer to a relationship gone sour: instead of a breakup ballad, the brothers turn heartbreak into a reason to make music. They open low, admitting "Basta con tocar el fondo" ["It's enough to hit rock bottom"], and spend the verses cataloguing the ways they numbed themselves — healing just to get sick again, chasing comfort just to unsettle someone else — before turning the pain outward: "Y quién te dio el derecho ilícito para opinar" ["And who gave you the illicit right to speak your mind"].
The hook is the whole thesis: "Canto por mí, mí, mí, que la garganta me delate" ["I sing for me, me, me, let my throat give me away"], "Yo canto por amor al arte" ["I sing for the love of art"]. Singing becomes the confession they couldn't make out loud — the art itself is the closure.
