This is a long-distance love song, and Lupillo Rivera sings it like a man who refuses to let the miles win. It opens with "estoy tan lejos de ti" (I am so far from you), then flips straight into defiance: "a pesar de la enorme distancia" (in spite of the enormous distance) he still feels her close, "alma con alma" (soul to soul).
The chorus keeps coming back to one stubborn idea: "No importa que estés tan lejos" (It doesn't matter that you are so far away). He talks to her in his head, tells her about his pain, and feels her kisses again. By the last verse the sky starts to get light, his eyes fill with sleep, and he says "contigo voy a soñar" (I'm going to dream about you). Then comes the bold part: "quieran o no, yo soy tu dueño" (whether they like it or not, I am your owner). It is a very ranchera way to say "you're mine", a bit possessive by modern standards, but that's the genre.
Great one for learners: "no importa que" + subjunctive ("estés") is a pattern you will hear everywhere.
