Where are the rest of my songs?
 

So I just recently started using limewire and I've downloaded a total of 51songs so far. All of these songs are shown in my limewire library in itunes and I want to put them in the actual itunes library. I read that to do that, you drag the song from limewire to itunes, however, my library in the limewire software doesn't show all the songs that I've downloaded: 37/51

Where did they go?!?!
