I have a first edition iPhone SE that shows and plays my complete Music library, some of which was purchased with iTunes, some ripped from CDs, and some purchased from Amazon music. I also have an second edition iPhone SE, which plays my music, but several albums and playlists have mysteriously disappeared from the Music library. My Macbook Air (2025, running latest edition of Tahoe) shows and plays only a small handful of music I recently purchased from iTunes. I just purchased a used iPhone (14 running iOS 27.2), and the Music library on it is incomplete and it will ONLY play the songs that I recently purchased (as referenced above) from iTunes.
What is happening? How can I get the complete library that exists on the first edition iPhone SE onto my Macbook Air and new phone?
I do not have a subscription to Apple Music. Is subscribing the only means available to restore all of my music to all of my devices?
A lot of the music on the first edition iPhone SE was purchased using an account that existed before Apple Accounts came into existence. I can still log into iTunes with the old account info.
