Soltarte comes from the verb soltar, meaning 'to let go' or 'to release', combined with the pronoun 'te' (you).
In this song, the lyrics express a deep regret for a past separation and a strong desire to not repeat that mistake. The line "prometo no soltarte" (I promise not to let you go) is a powerful declaration of commitment and a plea for a second chance, making soltarte a key word that captures the song's emotional core.
Have you ever met someone and tried to keep things casual, only to realize later you made a huge mistake? That's exactly what's happening in Ventino's song "Esta Vez". The singer admits they didn't plan on catching feelings, saying, "Sé que cuando yo te vi no esperé sentir / Ni volverlo personal" (I know that when I saw you I didn't expect to feel / Or make it personal). They held back so much, and now that the person is gone, all they feel is regret.
Now, the whole song becomes a powerful promise for a second chance. The singer is determined not to mess things up again. The main message is a direct vow: "Esta vez, te diré / Si nos volvemos a encontrar prometo no soltarte" (This time, I'll tell you / If we meet again I promise not to let you go). It's a song about realizing what you lost and hoping you get the opportunity to get it right the next time.
