What spanish song has to do with Superman?

I was at a nail salon in Costa Rica yesterday when a song came up to play. It was a girl singing and accompanied by an acoustic guitar, and it was sort of mellow. My spanish fluent amiga told me that it was a song I'd probably like, but she didn't remember what it was called. She said that the artist was singing something about her man being like a superman or so.


ring any bells?|||might be Super Man by Brown Boy
