“Robarte un Beso” (to steal a kiss from you) brings together two generations of Colombian pop: Carlos Vives, who made vallenato famous worldwide, and the young Sebastián Yatra from Medellín. They sing of a girl they've fallen for and dream of the moment they'll steal a kiss — playful, a bit shy, full of compliments.
The music mixes vallenato's accordion with pop and a light reggaeton beat, and the song was a big hit in 2017, especially in Latin America and Spain.
Both singers are very clear, so it's a good A2 song. Listen for the pronoun joined to the verb in the title (robarte = to steal from you), a pattern you'll see everywhere.
