Music

Hi 1387glenn,

It seems you're trying to share Music content with your wife and we can help.

How did she get this content on her iPhone?

If she purchased the songs from the iTunes Store, you can use Family Sharing to share purchases and download the songs to your iPhone:

Set up Family Sharing

Download family members’ purchases on iPhone

If she got this content from a computer, you'll have to sync with that same computer that has the content:

Sync your iPhone, iPad, or iPod using your computer

Best of luck.

Thanks for using the Apple Support Communities.
