Ajena is an adjective meaning 'belonging to another' or 'someone else's'. It carries a strong sense of possession and separation, often implying something that is out of reach or forbidden.
In "ULTIMAMENTE," the singer expresses a complicated desire: "Me gustas más ahora que eres ajena" (I like you more now that you belong to someone else). This word perfectly captures the bittersweet and often illicit nature of longing for someone who is no longer available, making it a powerful and intriguing word to learn.
This song is all about a guy who is completely losing his mind over an ex. He opens by saying, "Últimamente me entra la loquera" (Lately, I'm going crazy) because even though he's with "Un chingo de viejas" (a ton of women), he admits "ninguna me llena" (none of them fulfill me). He's trying everything to get over her, including drowning himself in parties and even listening to his mom, who says "que ni eras tan buena" (you weren't even that good). But nothing works. He's still obsessed, especially now that she's with someone else.
The whole mood shifts from heartbreak to a kind of reckless confidence. He's drunk outside her place, telling her he wants her more now that she's "ajena" (belongs to someone else). He's convinced her new guy can't compare, saying "No te toca como te toco" (He doesn't touch you like I touch you). He even hints at secret photos they took together "Sin ropa en el Merced" (Without clothes in the Mercedes), promising not to show them. It's a messy, dramatic story about wanting what you can't have and the crazy things it makes you do.
