Let me start off by saying that part of the reason I have stuck with Spotify for so long is because they don't fix what isn't broken - sort of speak, until recently!
I've noticed that my song library that used to be called "Your Library" or something similar has now been changed to be "Liked Songs" which is what some services such as Deezer and TIDAL have done and it's exactly why I don't use them. I find it irritating having to not only "love" an album but also the songs I like to that album individually to my music library and until recently Spotify never did this nonsense.
Until this is changed I'm probably going to become a free user because I don't agree with this change and unfortunately Spotify is the only music service I like; I have a royal hatred for Google Play Music, I don't like Apple Music (although it may be the last service to not have made this nonsensical change), I don't like Deezer or TIDAL, and so this left me with Spotify.
Time to go back to my personal collection of music, I suppose.
