How can I recover my playlists from older subscription?

Hello.

When I had a subscription to Apple Music, I created some playlists, which I would like to recover with my new subscription. It seams that the names of the playlists exists but songs cannot be found. I have just empty playlists. Is it possible to regain all the songs I added to them?

Thank you so much.

Season greetings.

blessing to all.

😊
