As is known to all, Apple Music encoded with M4P format is copyrighted. Even you pay for the option to download it to local drive, it can but be played on iTunes. Hence, there is no way to play Apple Music on Traktor DJ unless you use an
Apple Music converter [audfree.com] to convert Apple Music to common formats like MP3. Technically, such a tool can help you legally remove the copyright encumbrance from Apple Music and convert it to ordinary audio formats without quality loss. Like this, you can play
Apple Muisc on Traktor DJ [audfree.com] and any other device.
