Hi Julia, I hope this can help you. 1) Quisiera decirte al compás de un son (It's like "Quisiera decirte al ritmo de la musica". She wants to say something to the beat of the music). 2) This is hard Que respiro el aire Que respiras tú, (It's like "I breathe the air you breathe") no tienes remedio (I think this sentence needs the previous and the following to make sense ) Que respiro el aire Que respiras tú, no tienes remedio, eres mi gran amor (She tries to say that needs him to live) "I breathe the air you breathe, there is no way we can be separated, you are my biggest love" 3) Eres mis consuelos. (She tries to say that "you are my support", "you are my relief". She trusts him) 4) pare decirte que tu eres el amor de mis amores (para decirte que ...) The correct word is "para" not "pare".
