I came across this example sentence on spanishpod101 and just wanted to confirm that this is an actual idiom that is commonly used? the sentence was: más me gusta las milongas de aquel entonces a los nuevos tangos de hoy. from which i deduced the pattern "más me gusta X entonces Y" to mean "i much prefer X to Y". I could not find any such use for "entonces" in the dictionary hence my doubt that this could have been an error in the note?
