I had a christmas station last year, they we spent lots of time curating and tweaking. I dont think I deleted it, but it is no longer in my list, neither are the song likes/dislikes in my history.
Does a playlist get deleted if you dont listen to it for 9 months?
Why not offer a complete history of all song likes?
Why not offer a complete history that showed I did delete it on xx date? Then at least I can convince my wife we should stay subscribed becauise you dont randomly delete peoples data and lists...
