• "El Castigo" is Spanish for "the punishment." In a Songfacts interview with Los Master Plus frontman Alfredo Cabello, he discussed the meaning behind the song. "It talks about how when you're in a relationship and someone isn't there and they just leave you," he said. "You're talking about how big your love is, but you're still hurting, so it says, 'I hope the punishment that you're going to get isn't as big as my love for you, but it's going to be because it's horrible. I don't want it to happen but it's going to happen.' That kind of thing."
• The rapper Sabino, who is from the band's hometown of Guadalajara, Mexico, does a verse on this track.
• This is a more mature sound for Los Master Plus, but as usual, a mix of genres. "The song definitely has a hip-hop bass to it, like the beat and how the structure is, but it's mixed with a lot of Latin genres," Cabello explained. "It has a little bit of 'cha cha cha' and a little bit of salsa and a little bit of danzón, which is like an old genre from the '60s and '70s in Mexico. It's just a mixture of Latin stuff and modern mixed with hip-hop."
