I am a big fan of Spotify and have been using it for quite a while. Let me arrive at the point.
Under YOUR LIBRARY ---> ALBUMS, if I try to remove a song from it by selecting **Remove from Your Library**, it is no longer saved under my library but is still displayed under Albums with a plus sign to re-add the song to the album.
Wouldn't be great if the song is not displayed under Albums if don't want it, just like the functionality of playlists when a song is removed from a particular playlist by selecting **remove from this playlist**, it no longer appears in that playlist.
I think enabling this functionality will increase the aesthetics of the Spotify, it feels more clumsy now. I don't know the reason why the removed song is still displayed under Albums but any input is welcome.
