The other guy that gave that answer is a fud, don't listen ,theres an even easier way to do it!
Open Limewire! then go into library then click on saved files and then drag on to your desktop then put it on your MP3 ! $as easy as that$
Go to Itunes and click on file and click on import file or folder (single or album) find the song and then it will sync it on youre ipod.
Hope it helped (by Jamieson)
