Can't transfer from old ipod to itunes.

Greetings Gfirce70,

Thanks for visiting the Apple Support Communities! I understand you're unable to transfer music from your iPod to your library in iTunes.

With transferring music, iTunes supports syncing music from your computer to your device, and not the other way around. You can see this information outlined within the following support article: Sync your iPhone, iPad, or iPod with iTunes on your computer

Kind regards.

See Recover media from an iPod - Apple Community or Recover your iTunes library from your iPod or iOS device - Apple Community if you're referring to an iPod touch.
