It may have been user error, for me. I’m pretty sure CDs I had bought and ripped to ITunes changed to ‘this song is not on your device’ cloud copies when Apple Music happened- then they disappeared entirely, even though they were files I added to OG iTunes almost 20 years ago.

Sadly, my iPod’s hard drive failed a while ago. I enjoyed the free streaming stuff for the few and fewer times I had music on. I’ll be upgrading the iPod and heading out to sea… again.
