playlist delete

[user-removed]

I deleted the list to which the songs added when i marked +. Now when I add songs, they do not show up on any of the lists. This list can not be recovered from the profile.

Hi @user-removed and welcome to the Community! 🙂
The list that tracks marked with + get saved to is actually Your Library. This is simply called Songs on the sidebar. It's not considered a playlist so it would not be recoverable as one. This is also true for Artists and Albums.
Songs are not automatically added to any playlists unless you tell it to add to a playlist when you click the + sign. It will only store the info to the Songs, Albums and Artists library tabs.
I attached a screenshot of my iMac app and hope it helps clarify. 🙂
Have a good one!
