It says "I love you." It is missing any pronouns, and in that case this sentence just says "Love", however since korean is mainly a context based language, "I love you" is still the correct translation.
If the question is in plural :
¿Qué escuchan ustedes?
The answer have to be in plural too:
Nosotros escuchamos música.
