Entregarme means "to give myself over" or "to surrender myself." It's a deeply personal and vulnerable verb, implying a complete emotional or physical surrender.
In the context of the song, the singer expresses a fear of this complete surrender: "Pero no quiero entregarme y que algo muera en mí" (But I don't want to give myself over and have something die in me). This reveals a struggle between desire and self-preservation, making it a poignant and relatable word.
This song from No Te Va Gustar, "A las Nueve (En Vivo)" [At Nine (Live)], is all about that gut-wrenching feeling when you know someone you care about is about to leave, and there's nothing you can do to stop it. The singer sees this person arrive and immediately knows their time together is limited: "Solo me das en un rato lo que tenes para dar" [You only give me in a little while what you have to give]. It's a really blunt and honest look at a relationship where one person is clearly more invested, or perhaps just more available.
You can feel the desperation as the clock ticks down. The line "Sé que te vas a las nueve, sé que me muero a las diez" [I know you leave at nine, I know I die at ten] perfectly sums up that dramatic, heartbroken feeling. Even though the singer understands the situation ("Ya me explicaste mil veces, lo que veo es lo que sos" [You already explained a thousand times, what I see is what you are]), it doesn't make the parting any easier. It's a powerful song about accepting a difficult truth, even when it breaks your heart.
