Many thanks for supporting my work and providing the screenshots with your question! The first screenshot shows that the files in question are all **M4P** files (I've adjusted the topic title accordingly). M4P is Apple's **DRM-protected** version of MP4/M4A which is not unfortunately supported by Mp3tag. There was a time where you could exchange the DRM'ed files with "free" files I think via iTunes Match, but I don't know how this is working now with Apple Music. There are lots of third-party tools that claim to remove the DRM, but I guess most of them simply re-encode the file which is a lossy process. --- _[View the full topic](https://community.mp3tag.de/t/m4p-files-wont-load-on-mac/55364)._
