Entregado is the past participle of the verb entregar, which means 'to deliver' or 'to hand over'. In a romantic song like this, it takes on a much deeper meaning: 'to surrender' or 'to give oneself completely'.
When the singer says, "que me he entregado a ti" (that I have given myself to you), they are expressing total vulnerability and deep emotional investment. It's a powerful, dramatic word that captures the feeling of giving your whole heart to someone, making the pain of being abandoned even more profound.
This song is a classic Cumbia heartbreaker from Mexican legends Los Ángeles Azules! It's all about someone begging their partner not to leave. The singer lays it on thick right from the start, pleading "Ahora más que nunca / Te necesito junto a mí" (Now more than ever / I need you next to me). They feel like they've given everything to this relationship and now they're facing total devastation, even saying "No podré sobrevivir" (I won't be able to survive) without their lover's warmth. The best part is that while the lyrics are full of despair, the music makes you want to get up and dance. It's the kind of song you can cry and dance to at the same time.
The feeling shifts from begging to bitterness. The singer accuses their partner, repeating how "Es fácil para ti el abandonarme" (It's easy for you to abandon me). The real sting comes when they realize they were never that important to their lover in the first place. It hurts to know, they sing, "Que he sido un paso más / En tu sendero de amor" (That I have been just one more step / On your path of love). Ouch. It's a simple, direct song about feeling used and left behind for no good reason.
