Why does Sophocles Papas not name the Fernando Sor pieces in "60 short pieces for guitar "?

He simply refers to them as, Andante or Minueto or Allegro or Waltz. Why why why? I know a few of them by name but I would like to know the names of all of them.

Check online, perhaps Wikipedia or a CD shop / website that specializes in that kind of music will tell you.
On the other hand, the songs might not even have names.
