@Mrsladyj Nice to see you around the Community!
I'm showing your account is currently set up with the free service. The option to play your thumbed up tracks on demand would only be possible with a Pandora Premium subscription.
If you upgrade to Pandora Premium, we will automatically generate separate Thumbs Up playlists for your collected stations (including your Christmas ones).
You'd then be able to listen to each playlist separately, or create a new playlist where you combine all of those tracks into one place.
If you'd like to upgrade to Pandora Premium, or for more information, check out this page here.
Hope this helps!
