How can I download music on shuffle？

Hello, as a user who has been using shuffle for 6 years, I found a problem after the supply of shuffle has been stopped for a long time. Does shuffle not consider how users import music when developing? When the music downloaded from Apple music is imported through iTunes, it is told that it cannot be copied. It needs to be downloaded by the iPod itself, but shuffle has no screen. How can I use the music of Apple Music? Can only download through other music software? I can use Apple Music on my iPhone but not on the same company's shuffle. Other music software songs need to be downloaded by members, even if the download is successful, it is not the MP3 format that shuffle can read. Is the original design of shuffle a U disk? Apple's products have a very long service life. As a small MP3, I think the service life of shuffle can reach 10 years, but now I lose the significance of using shuffle because I can't download music. How can I download music on shuffle？
