Tell me how it goes.
you download all the songs you want, then you go to the library section of limewire, then at the bottom of the screen theres a button that says explore, and you hit that
a window will pop up, and you open your itunes, and drag each song to your itunes library
its really easy actually
If what you're downloading is legal, and in mp3 format, I believe so. Import it into itunes to know for sure though.
