Obsesionao is a colloquial, shortened form of "obsesionado," meaning "obsessed." It's a more casual and modern way to express intense preoccupation.
In the song, Ramón Vega uses it to describe his overwhelming feelings, singing, "Terminaría yo obsesionao de ti" (I would end up obsessed with you). This word captures the intense, almost unavoidable nature of his infatuation, making it a relatable and engaging choice for learners.
"MiMywAY 3" is Ramón Vega missing someone before they've even left. He starts the song already aching for her, listing tiny details he loves: her nails, the little beauty marks on her skin. He admits he doesn't understand why not seeing her for one day feels like a year.
The chorus repeats like a confession: he's jealous of every mirror she looks into, because it gets to see her and he doesn't. He dreams of collecting two thousand kisses to save up for the days she's gone.
In the second half he pictures standing in Times Square, saying she outshines every light on the block, and jokes that he smells like cologne ("a My Way") just from thinking about her. He knows some people, including her mom, might judge him for being a singer who spends his nights dedicating little songs to her, but he doesn't care. It's a simple, honest love song about someone who would rather feel this kind of longing than not feel anything at all.
