want to download onto an mp3 player

Hello leigh5w,

Thanks for posting on Apple Support Communities. We see that you want to sync an iTunes library or Apple Music library to an MP3 player. iTunes and Apple Music only sync content to Apple devices such as the iPod, iPad, and iPhone. iTunes- Apple. If you have an Apple device check out this resource for guidance on how to sync with iTunes: Sync your iPhone, iPad, or iPod using your computer.

Otherwise, there is most likely specific software that your MP3 player uses to sync content to it. And there may be a way you can manually copy music from your library to it. We suggest reaching out directly to the manufacturer of your device to obtain further information.

Cheers!
