Q: I want to transfer My a playlist "mobile transfer" from iTunes to my new phone

Hello phillyfanEd96,

Thanks for using Apple Support Communities.

If you want to put an iTunes playlist on to your iPhone, then either sync or drag the playlist, depending on how you normally move content to it.  Directions for both processes are linked to below.

Sync your iPhone, iPad, or iPod touch with iTunes using USB

Move content from iTunes on your computer to your iPhone, iPad, or iPod touch

Have a good one.
