You can PM me if you want a clear explanation.
Is she having trouble importing her CDs to iTunes?
Is she downloading the songs (buying them) off iTunes or another website like Myspace?
Does she already have the songs in her music library on iTunes and they're not transferring to the ipod?
I need to know what exactly the problem is and I'll help you the best I can..
and no, you don't have to buy the songs over the internet.
