I’ve been converting tracks in Apple Music on my Mac to MP3 files that can then be exported and saved elsewhere. This can’t be done with some. I remember reading somewhere that tracks bought before a specific date can’t be converted. A DRM issue if I recall correctly.
While using the old PC for ripping CDs I discovered that in fact most, if not all, those older purchases are in iTunes on this machine. And are in an exportable format. Along with many albums from CDs which I had evidently copied to ITunes back in the day. This is going to save me a lot of work.
