When there is a change of subject in a sentence, a subjunctive is required in Spanish. For example: I want you to... / we need you to... / you would like me to...In Spanish, we would say something like "Quiero que..." / "Necesitamos que..." / te gustaría que.. all followed by a subjunctive in the correct person. a subjunctive would be required in the sentence; "quiero que ESCUCHES esta canción". this translates literally to, "I want that you listen to this song".
