All my problems are in my phone Music app, my laptop Music app seems the same.
My problem started 5 days ago, Feb 10, 2025. iPhone automatic update on Monday to iOS 18.1 and the next day was unable to add a new album. Did a Sync in Finder window and went from 74,647 songs down to 10, one single album. I was on Sonoma still on laptop and tried multiple things to recover using different Sync options and then got to 1870 songs on the phone. Playlists seem to have been completely corrupted and when I deleted a newly detected playlist simply called Playlist, it deleted a different playlist with over 15,000 songs in it. That’s gone forever, thanks Apple. In discussion with Apple tech for two days, we tried another Sync method which got me to 60,000+ songs, most of which were greyed out on the phone app. I upgraded laptop to Sequoia last night and ran a Stnc again, now I have 67,000+ songs but behavior in the Play Banner still flashes through a dozen songs before stopping on desired song, but seems to be working. I had so many issues I can’t remember or list them all such as half of an album being out of Country or Region, so I’ll be exploring for more of those issues in the next couple days.
At this point, I think there has to be an alternative app to use to manage my own music and would love any ideas on that..!!!!!!!!!
