Sobran comes from the verb sobrar, which means to have more than enough of something or for things to be left over.
In this song, Esteman sings "Razones me sobran" (I have more than enough reasons) to express his complete certainty about taking a leap of faith for love. Learning this unique verb will instantly make your Spanish sound much more natural and expressive.
This song is about that incredible feeling when someone new comes into your life and just clicks. Esteman sings about a love that's so powerful, it feels like it has changed his whole reality. He tells this person, "Porque tú cambiaste mi universo" (Because you changed my universe), and that they bring him a peace he never knew he could have: "Despiertas esa calma / Que no sabía / Que un día llegaría" (You awaken a calm / that I didn't know / would one day arrive). It's a deep connection that works even from a distance; he feels their presence even when they're far apart.
The central idea is a beautiful invitation to take a risk together. He sings, "Sabiendo que no te gusta nadar / Igual quiero saltar" (Knowing that you don't like to swim / I still want to jump). He's asking them to leap with him into a "mar que se extiende" (a sea that extends) full of "posibilidad" (possibility). It's a sweet admission that even if they're scared, being together is the only reason he needs to face the unknown.
