Añejaíto' is a colloquial, diminutive form of añejado, meaning 'aged'. It's often used to describe things that have matured over time, like wine or cheese, and implies a richer, more refined quality.
In this song, the artist uses it to describe love: "Espero que el amor te guste como a mí, añejaíto' como el vino" (I hope you like love like I do, aged like wine). This unique usage suggests a desire for a deep, mature, and lasting love, rather than a fleeting romance, making it a memorable and intriguing word choice.
Lenny Tavárez is completely smitten in "SENTIDO COMÚN"! He's just met someone and, after a few words, he's convinced she's his destiny. He even wonders, "¿Por qué será que el sentido común Es el menos común de los sentidos?" [Why is common sense the least common of the senses?] because he's throwing all caution to the wind. He's not thinking "ni un poquito" [even a little bit] and is ready to go all in.
He's dreaming big, wanting to "pego a besos to' los pedacito' rotos" [kiss all the broken pieces] and turn every "yo" [I] into "nosotros" [we]. He even imagines their future baby having her face! But then he brings himself back to reality, asking, "¿pero qué pasaría si fuera por ti?" [but what would happen if it were up to you?]. He's captivated by her every move and admits, "Yo ni sé si tú eres lo que me conviene Pero to' los pensamientos me los tienes de rehene'" [I don't even know if you're what's good for me, but you have all my thoughts hostage]. It's a fun, passionate look at falling head-over-heels, even when common sense tells you to slow down!
