I tunes music transfer to I Phone
I have a treasured music library on my Dell laptop. All the music is paid for either from Apple or loaded from personal CDs. I have an I phone 8 plus. I can see both libraries on my laptop (see images of each) I can see the music currently on the I phone and the music currently on my I tunes on my computer. How do I get all my music onto my I phone?
