Converting Limewire Music already in itunes to the main library
 

Ok, this is driving me insane. I have music downloaded from limewire on my old computer and when I got my new computer and reloaded limewire it just showed up in my itunes but I can't get it to go into my library. I can play it but I can't move it at all. Can anyone please help me.

It's all explained here how to "properly" add those song files to iTunes Music Library: How to transfer music to my iPod (& iTunes)
