I agree, I don’t need recommendations from my own library. I know when I am in the mood for a particular album, and if not, it’s much more pleasant to glance through my Artists list than to trust some jerk at Spotify to tell me what I want. Especially since they are now actively trying to replace the music on their mood playlists with royalty-free stock Muzak.
For discovery, there are plenty of (especially linear) streaming music sources that are dirt cheap or free, anyway.
