Abolengo refers to a person's lineage or ancestry, often implying noble or distinguished origins. It's a less common word that adds a touch of formality and historical depth to the lyrics.
In the song, the artist sings, "Pensé que me querrías aunque no fuera de abolengo" (I thought you would love me even if I wasn't of noble lineage). This reveals a poignant insecurity about social status and the desire for unconditional love, making the word particularly impactful in conveying the song's emotional core.
"Popular" is about never quite fitting in. The singer looks back on being an outsider at school, misunderstood by people who had no patience for anyone different, and leans on music as the thing that gets him through it.
The second half turns to a specific kind of heartbreak: loving someone who never saw him as more than a friend. He hoped she'd love him without caring that he wasn't from money or status, but she kept him at arm's length in comfortable, lukewarm friendship instead.
It's a song for anyone who's felt overlooked, wrapped in Zoé's warm rock sound rather than self-pity.
