My Question or Issue

Has been happening for years - I keep finding that songs that I know with certainty I have added to my library (songs I have Liked) are getting un-liked/removed from my library. This undermines my confidence that the library I've curated is complete. Is there a way to stop this from happening?

its been 5 years on this thread alone. If anyone needed proove that all these "product managers" that are all about "user experience" at spotify are kidding themselves, this is it. Spotify users curate their playlist over years, like for me personally close to a decade now. Maybe its just me, but I care about my songs, they are important to me, is that really unreasonable ? And yet I know that all the time, songs disappear from my collection, lots I will never find again.
Call me crazy but this is unacceptable ? Get it together Spotify.

I cancelled my subscription last week. This was one of the biggest reasons
but I also saw they were raising the price of subscriptions in the uk.
Radio has been doing just fine for now.
