When Apple introduced the new iPods, many users were disappointed that the players could not play music from Apple Music and the players thus lost their meaning according to many. In the editorial office, we are also of the opinion that at least the iPod nano could have received limited support for music in the M4R format, in which music from Apple Music, as it has a display and is much "smarter" than the iPod shuffle. But we waited in vain, iPod nano and iPod shuffle are models that do not support the new service at all, and those who want to enjoy prepaid music have to switch to iPod touch or iPhone. But why is that?
According to close sources 9to5mac the reason is very simple - Apple doesn't want people pirating music in such a way that they have it on purely offline devices and can listen to it even after canceling their membership Apple Music or their prepaid period ends. Apple as it has not currently developed a way to listen to a song on an iPod nano or shuffle. Conversely, devices with a system iOS they are regularly connected to the Internet and the device can contact them remotely Apple and verify that the user has a valid membership. On the other hand, it is possible that if the company is interested in iPods as it was a few years ago (which we already doubt), it will invest in the development Apple Music DRM system also for iPod shuffle and nano. This could work similarly to games within PlayStation+. If you download a game as part of a PS+ membership and move it to a PSP that has never otherwise been connected to the internet, the game will still have the date information stored and the game will simply stop working after the date has passed. This system cannot be fooled even by changing the system time on PSP.

That iPod shuffle only has 2GB of memory and people use it for sports. Even if a person cancels their membership, the few hundred songs left there won't ruin anyone. The next time I connected to itunes, itunes could have deleted them by itself.
