DRM Free Music With iTunes Match & Apple Music?
When using iTUnes Match you will be able to download a copy of your mp3 file (256 Kbps) from iTunes servers directly to your devices DRM-free.

If your file B.mp3 doesn't match any B.mp3 file on iTunes servers, then your file is uploaded to your iTunes Match account (same quality as local file) and it can be downloaded on other devices DRM-free. 

Every file available on Apple Music has DRM, meaning: all the files you save for offline listening aren't DRM Free. Also, some files on Apple Music aren't available in every region.

Hope this helped!
