transfer non-apple-purchased music from computer or internet to 8th gen iPad 10.2
I am about to purchase either a most recent gen iPad 10.2, or possibly a12.9 refurbished 4th gen iPad pro mostly for the purpose of drawing and working with image and animation. Is that latest gen 8 or 9?
I have a few questions but will start with 2 music related questions.
1)Is it possible to transfer non-apple-purchased music from my MacBook pro computer to latest gen iPad 10.2 or 2) from internet to latest gen iPad 10.2 ?
Is either process easy? Is either process difficult. Apple seems to have more barriers to moving music, even what I own on cd to iPhones and I wonder if it is the same for iPad?
