Tarah;
I use DVDVideosoft.com it was a free download. Once I downloaded the program it created a file in my documents, which you could move to your desktop if you would prefer.
When I copy music I open the the file DVDvideosoft in my documents, then I open my itunes highlight the song I want and drag it to the open DVDvideosoft foler. From here I open the program from the shortcut that was created on my desktop when I downloaded. I open the program select the Audio converter button…click that and then click on add files, it opens the folder DVDvideosoft in my documents then I click on on the song I want to convert and the rest is then done for you… it then converts the song and keeps it in the file folder.
I hope this helps you.
