Given how Apple Music has completely fucked up my wife’s music collection, I can’t imagine them being able to unfuck your situation at all. So sorry.
oh man, I started with iTunes Match because that's the only service that I could use to backup all my MP3s, and now it's all messed up and so much music has just disappeared from my playlist... so sad.
Unfortunately I still don't know a service I can use that will allow me to sync my current MP3s / what I have in Apple Music, and export it if I need it. There's really an issue of owning data and being able to take it elsewhere :/
Same story here. I'll never go back to Apple Music, even if only for streaming. I had hundreds of tracks and albums just demolished by something related to iTunes Match, didn't realize for months, and didn't have a solid backup system at the time.
