Sobra comes from the verb sobrar, meaning 'to be left over' or 'to have an excess of something'. It’s a fantastic word to express abundance and is much more passionate than simply saying 'I have'.
In this classic ballad, Luis Miguel proudly declares, "Me sobra mucho, pero mucho corazón" (I have a lot, a whole lot of heart to spare). He uses this word to say his capacity for love is so immense that it's overflowing, contrasting it with his lover's calculated and conditional affection.
Have you ever felt like you're being interviewed for a job you already have? That's the feeling at the center of this song. The singer is getting grilled by his partner about his past, as if she's looking for a reason to stay or go. He calls her out directly: "Pides cariño, pides olvido / Si te conviene" (You ask for affection, you ask for forgetting / If it suits you). He's tired of this conditional love and even tells her, "No llames corazón / Lo que tú tienes" (Don't call what you have a heart). It's a pretty bold statement!
Instead of answering her questions, he tells her what real love is. For him, it's not about digging up the past; it's about faith. He defines true affection as being willing to "Dar por un querer / La vida misma sin morir" (To give for a love / life itself without dying). He doesn't need a logical reason to love someone. As he proudly declares, "Yo para querer / No necesito una razón / Me sobra mucho / Pero mucho corazón" (To love / I don't need a reason / I have plenty / a whole lot of heart).
