To my opinion, DRM Media Converter is better than other similar product. It works faster, and can remove DRM from iTunes purchased and rental movies/TVshows. The most valuable for this app is that it can easily remove the DRM protection from Video and audio files as well as Ebooks purchased or downloaded from iTunes. There is no quality loss at all in the output videos, audio or ebook.
Apple Music is encrypted with the digital right management (DRM), so you can play your Apple Music on the authorized devices only, I recommend you can use a professional software named Audfree DRM Audio Converter to remove the DRM protection, after converting work you can unlock protection from Apple Music and save them as other common formats.
