transfer music from iPod 2005 to touch iPod 7

Transferring music from one iPod to another is not possible. If you have Apple Music or songs purchase from iTunes or iCloud music library they will show up on the new iPod when you sign in to your account and enable Apple Music/Sync. Songs that are on a computer will have to be transferred from that computer to the iPod.

Transferring music from an iPod to a Mac is not possible either. The iPod is synced with a library on a computer where the music is transferred from the computer onto the iPod. Transferring back from the iPod is not possible. To get the music on the new iPod, connect it to the computer that contains the iTunes library that was used to sync the old iPod.
