--Cytat (fatih):
I think that you cannot learn any language by listening to songs, at least when you are an absolute beginner. When you are intermediate, you can start listening to songs and the news to emprove that language, though news will be, in my opinion, more useful than songs.
--Koniec cytatu
I must agree with It now, because with English song situation is same. So, first thing, if I know one language very well is to read some books, who reads previously in one language (Your native language) and after that I'll move on.
But yes, as an absolute beginner is good choice to know some basic phrases, grammar and vocabulary.
Also, I am interrested to Polish language too, because It is similar to Slovak.
