Changing ALL of my music from my old Ipod to the new one. Not just the purchased songs
I received a new ipod and want to change ALL of my music, 2,000 songs, over to my new ipod. Going to the itunes store it will only download purchases ive made through itunes store. What ive done to try to get the rest is update my computer, the apple store, both ipods, turned off and on everything. went to Properties and changed the preferences to not to sync automatic to auto and to sync all of the music. Its been about 5 hours and all of that gave me nothing. Then i called apple and the guy said because it is songs not from Ipod there is nothing to do for it. Please help, thank you
iPod, iOS 15
