Music is no longer playing in Apple Music Sonoma 14.4.1

I have a ticket open with Apple since early April. Sounds like same issue as you describe. Escalated to a senior technical group. After some troubleshooting and providing some additional data, Apple acknowledged their engineering team was looking at the issue but no timeline. Got an unexpected call about a week later with an 'update' but the call dropped. Have not heard back from my technician (emailed ~Monday 4/22). In the dropped call sequence, they were directing me to add 'the app' to Settings/Privacy & Security/Files and Folders. That is where the call dropped. Music is already on the Files and Folders list but OneDrive is not and (for me) there isn't an option to add additional apps (the + button is missing from Files and Folders). So I am just waiting for the technician to call back. As you point out, it works everywhere else including my iPhone so it isn't like all my music is inaccessible. Just on the Mac. Service has been better than expected until this week. Will post an update if my issue gets resolved.

I'm having the same issue. All my music works fine on my iPhone 15 iOS 17.4.1 my Apple TV tvOS 17.4 but will not play on my Mac Studio 2022 running OS 14.4.1 Apple Music is 1.4.4.48 I just bought the new Judas priest album and had trouble downloading it so I restarted the mac studio I was able to download. Not sure if the music played before the restart. all movies downloaded from iTunes store play and sound is fine just music won't play. Both music from my CD collection as well as music from the iTunes store. If I click the play button on to file in the finder the song plays fine. Frustrating!
