This question is more about iTunes than the iPhone.
If I have put all my CD's on my computer for my music library, can I just copy those folders/files to a CD (or DVD) and then copy them to my wife's "My Music" folder? Will iTunes recognize and import the songs? Or are the songs somehow "coded" for my computer?
Basically, we are trying to avoid her having to go an import every CD like I did.
You could even make it easier by using an external hard drive or jump drive. The songs are not coded to your iTunes library specifically. The only ones that are account specific are tracks that you have purchased from the iTunes Store.
