Learning Norwegian

I found that if I repeatedly played a song with the cd playing it, it didn´t matter if I knew the chord´s names or anything, because later I can play the song perfectly all by myself. So, in this case, how I am suposed to learn phrases that I don´t understand? For sure I can know that "Ja" is "Yes", but I have no idea where is the "don´t speak" in the phrase: " Beklager, jeg snakker ikke norsk" . So i´m using the method. I repeatedly play the mp3 file in my iPod and let my ear accustom to the sounds. I can say without problems " Kan du hjelpe meg? " and I know I´m saying "Can you help me?" because it sounds...
