The song "Mentira" (Lip Service) by Elvis Costello & The Attractions featuring Pablo López is a collaboration between the English singer-songwriter and the Spanish artist. The lyrics talk about deception and the desire for excitement or something thrilling. The song begins with the phrase "Dejaste el coche en marcha" which translates to "You left the car running." This line may symbolize someone who is always on the move, never stopping or taking a break. The song describes this person as brilliant but in an unhealthy or insane way, urging them to leave behind their delirious self for today. The chorus emphasizes the theme of wanting something exciting. "Todo el mundo quiere algo emocionante" translates to "Everyone wants something exciting." However, there is uncertainty about whether the subject of the song actually desires this excitement. The lyrics continue to express that everything the singer does or that the listener will see is a lie. It becomes difficult to understand or comprehend this deception. The mention of sending a postcard signifies the desire to know what the other person wants from the narrator. The song concludes with the repetition of wanting to know what the other person wants through the line "Y manda una postal, quiero saber qué es lo que quieres de mí." Overall, "Mentira" explores themes of deception, confusion, and the longing to understand someone's intentions.
