Aplauso means "applause" or "clapping". While it might seem like a common word, its use in this song is particularly striking and emotionally charged.
Cristian Castro sings, "Pido un aplauso para el amor que a mí ha llegado" (I ask for applause for the love that has come to me). He's not just talking about a literal clap; he's celebrating a profound new love that has transformed his life, leaving behind past sorrows. This makes the word feel grand and celebratory, inviting listeners to share in his joy.
This is Cristian Castro's take on a José José classic, recorded as a duet with José José himself, "El Príncipe de la Canción," for the 2010 tribute album Viva El Príncipe. The whole song is one long exhale after a breakup. The title line does the work up front: "Ya lo pasado pasado, no me interesa" (what's past is past, I'm not interested), and Castro spends the next verses proving he means it, repeating "Ya olvidé" (I already forgot) like he's talking himself into it as much as anyone else.
The turn comes when he stops looking backward and names what's in front of him: "Pido un aplauso para el amor que a mí ha llegado" (I'm asking for applause for the love that's come to me). That's not subtle, and it isn't supposed to be, it's a bolero built for a big, unembarrassed declaration. By the closing "Ya le dije adiós" (I already said goodbye) to the past, the song has done exactly what its title promised.
