If it's enough for you just in a nutshell then the first one is set in Middle Ages scenery, it's about brave but obedient and humble life of common soldiers who have to follow their king and fight against those he, the man of authority, wishes. The other one is probably supposed to be funny, it says, in examples, how naive and possibly dangerous it is to believe horoscope predictions. But you won't get more from me, I'm horrible at lyrics translating and moreover, I dislike both the lyrics and the music. And
the way of singing.
