Esmeril literally translates to "emery" or "grinding wheel." It's a very uncommon word to find in song lyrics, especially in a romantic or sensual context.
In this song, Myke Towers uses it in a suggestive way: "Se lo hago como un esmeril" (I do it to her like an emery/grinding wheel). This implies a rough, intense, or perhaps even abrasive action, adding a raw and unexpected layer to the song's intimate moments. It's a memorable and intriguing choice that stands out.
"ISLA" is Myke Towers doing what he does best: turning a compliment into an invitation. He opens with "Tú eres muy bonita como para estar solita" [You're too pretty to be alone], and from there the whole song is one long pitch to get her on a plane to Puerto Rico. He isn't subtle about the details either: "Te bajo pa' PR" [I'll bring you down to PR] and "Te traigo viaje' privado' con el pilot" [I'll bring you a private trip with the pilot] before naming the actual spot, "Cerca del lago, tú y yo en Condado" [Near the lake, you and me in Condado], the lagoon-side neighborhood in San Juan.
The island itself is the flex here. "Si tú quieres, pa' la isla te viajo, baby" [If you want, I'll travel to the island with you, baby], he says, treating a trip home like the ultimate move. It's a short, direct come-on built for a beach day, not a love song with much more going on underneath it, and it doesn't pretend to be.
