While nota can literally mean a musical 'note' or a written 'note', in this song it's used as popular slang for a 'vibe' or a 'high'. It describes a specific state of mind, often an intoxicating feeling.
In 'Nota de Amor', the artists aren't singing about a written message. They sing "No hay quien me quite esta nota, que estoy sintiendo por ti" (No one can take this high/feeling from me, that I'm feeling for you), describing the powerful and addictive 'high' of being in love. Understanding this one word is the key to unlocking the whole meaning of the song!
Think of the kind of crush that hits you so hard it feels like a physical high. In "Nota De Amor", Puerto Rican reggaeton powerhouse Wisin teams up with Colombian icon Carlos Vives and Daddy Yankee to talk about being completely hooked on someone. The title plays on Spanish slang right away: while nota literally means a written "note," the phrase estar en una nota means being buzzed or on a euphoric high. Carlos Vives belts it out in the chorus: "Vivo en la luna por ti, vuelo sin alas por ti / No hay quien me quite esta nota" ("I live on the moon for you, I fly without wings for you / Nobody can take away this high"). It is big, dramatic romantic energy where ordinary life fades out and love feels like a cure that fixes every headache.
The verses dive straight into everyday domestic bliss mixed with total surrender. Wisin plays the devoted partner who is ready to marry her right now: "en el bolsillo ya tengo el anillo / Es muy sencillo, si fallo le pido perdón y me arrodillo" ("in my pocket I already have the ring / It's very simple, if I mess up I apologize and get down on my knees"). He is cooking paella and watching her walk down the hallway in yellow underwear, completely smitten. Then Daddy Yankee steps in to declare that none of his wealth matters compared to this feeling, dropping the line: "ni los diamantes, pulseras / Lo que pesa mi chequera / Vale más que bailar contigo un vallenato" ("neither diamonds, bracelets, nor what my checkbook weighs is worth more than dancing a vallenato with you"). Here, he nods to Carlos Vives' native Colombian folk rhythm, vallenato, reminding us that a simple slow dance beats any bank account.
