Hi Leonidas. If you had an Apple iPod, you should have an iTunes account. If you can access that account, your would be able to buy a new iPod and move your library to it. I did the same thing many times.

If that doesn’t work, you may just want to pay for an Apple Music account. Gives you access to millions of songs and you can create your own library, playlists, etc. Buy the time you purchase a lot of random CDs, download them, etc. you would be better off with a music account.
